Course Overview

This course provides a comprehensive overview of Design Patterns in C# and .NET from a practical perspective. This course in particular covers patterns with the use of:

  • The latest versions of C# and the .NET framework
  • Use of modern programming approaches: dependency injection, reactive programming and more
  • Use of modern developer tools such as ReSharper
  • Discussions of pattern variations and alternative approaches

This course provides an overview of all the Gang of Four (GoF) design patterns as outlined in their seminal book, together with modern-day variations, adjustments, discussions of intrinsic use of patterns in the language.

What are Design Patterns?

Design Patterns are reusable solutions to common programming problems. They were popularized with the 1994 book Design Patterns: Elements of Reusable Object-Oriented Software by Erich Gamma, John Vlissides, Ralph Johnson and Richard Helm (who are commonly known as a Gang of Four, hence the GoF acronym).

The original book was written using C++ and Smalltalk as examples, but since then, design patterns have been adapted to every programming language imaginable: C#, Java, PHP and even programming languages that aren't strictly object-oriented, such as JavaScript.

The appeal of design patterns is immortal: we see them in libraries, some of them are intrinsic in programming languages, and you probably use them on a daily basis even if you don't realize they are there.

What Patterns Does This Course Cover?

This course covers all the GoF design patterns. In fact, here's the full list of what is covered:

  • SOLID Design Principles: Single Responsibility Principle, Open-Closed Principle, Liskov Substitution Principle, Interface Segregation Principle and Dependency Inversion Principle
  • Creational Design Patterns: Builder, Factories (Factory Method and Abstract Factory), Prototype and Singleton
  • Structrural Design Patterns: Adapter, Bridge, Composite, Decorator, Façade, Flyweight and Proxy
  • Behavioral Design Patterns: Chain of Responsibility, Command, Interpreter, Iterator, Mediator, Memento, Null Object, Observer, State, Strategy, Template Method and Visitor

Who Is the Course For?

This course is for .NET/C# developers who want to see not just textbook examples of design patterns, but also the different variations and tricks that can be applied to implement design patterns in a modern way. For example, the introduction of the DLR allows us to use an ImpromptuObject, so that our DynamicObject exposes any interface we desire. This allows for dynamic programming, and many design patterns are presented in terms of their static and DLR-based variations.

Presentation Style

This course is presented as a (very large) series of live demonstrations being done in Microsoft Visual Studio. Most demos are single-file, so you can download the file attached to the lesson and run it in Visual Studio, Visual Studio Code, Rider or another IDE of your choice.

This course does not use UML class diagrams; all of demos are live coding. I use Visual Studio, various NuGet packages, R# unit test runner and even dotMemoryUnit.

Curious how to solve common problems in your code? Want to learn more about design patterns to prepare yourself for a technical interview?

Then you came to the right place :).

The objective of this course is to introduce you with all the design patterns that can be implemented in Java.

In this course, you will learn everything about design patterns from each of the three main categories: creational, structural and behavioural.

The main target of this course are beginners which are making their first steps in learning Java programming language. The course is also targetting more advanced students which need to brush up their knowledge on the topic of design patterns.

What is a Design Pattern?

A design pattern is a reusable solution that can be applied to common programming scenarios. As a developer, you will encounter design patterns everywhere. The Java API alone solves most of its programming challenges with different design patterns.

The term has been introduced in the book called Design Patterns: Elements of Reusable Object-Oriented Software, a book published by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides, a group of computer scientists known as the Gang of Four. 
I hope you will find this course useful and you will use the knowledge gathered from this course in solving design issues in your code.

Object oriented design patterns help you create more robust and flexible software. In this course I will show you how to use these patterns in TypeScript.

Design patterns are best practices that will help you solve common problems in programming. There is no need to solve a generic problem that has been solved many times before.

Simple example: how do you write a system that allows user to order a product and customize some of its features? There are many possible solutions but they probably won't be as flexible as using a decorator pattern.

From this course you can learn GoF Design Patterns with detailed Java examples.

There are a lot of other courses in this topic. So, why would you choose exactly this course?  Here just a few reasons:

- Coding examples

To learn programming it is not enough just watching videos and reading books. You also need to have a lot of practice. In this training course you will review multiple practical tasks and coding examples which will help you learn and understand Java better.

- Open source code

We hide nothing from our students! Including the source code for the hometask solutions and source code of examples which were shared during the lesson. Having the source code you can just copy and paste it to run it on your local computer to understand how things work better.

You are allowed to use all source code examples for learning purposes. This helps significantly to configure environment and make tests work, especially in case student didn't work with any testing framework in the past.

- Q&A support

The significant difference between online and offline learning process is instructor's availability. If you are in the one room with tutor he always can help you to get understanding specific concept or to help fix your code on your computer.
In this course, we are supporting students with answers to any questions flagged in Q&A section. In case there will be recurring questions - separate video lessons will be created to show how to address issue.

So with this course you are not just getting video materials, code exercises, source code, access to free mobile application without limits (which is still pretty cool, huh? :) ) , but you also get tutor support and answers to your questions along with this course.

- Relevant knowledge

After our team investigated other Java courses on Udemy we realized that most of them has nothing in common with real life. Information which is shared there is very old and significantly out of date. For example, instructor teaches framework which is not used already for 15 years. Or instructor do a stress on the programming design which is not used anymore at all!

Instructor of this course is consultant in the top-rated IT outsourcing company and helps to bring cutting-edge solutions in IT for all his clients. Feel free to check LinkedIn page of instructor and check skills endorsement. More than 19 thousand people acrooss all over the world (BTW most of them are from top 100 companies of the world) evaluated skills of Andrii Piatakha.

With this course you can be sure that you will spend your time learning the right things from the one of the best IT consultants in the world.

- Free mobile App without limits for our students

Knowing Java is one skill. Be able to pass interview in company - that is another skill :) Nowadays a lot of companies use tests to select candidates on the first level of interview. We developed application to practice skills specifically for such purposes.

In this course we will provide you link to download our FREE mobile app for android. (soon it will be also available for iOS platforms)

Instructor of this course come up with hundreds tests which are used to test knowledge of candidates. With this application you will be well-prepared for the interview.

Also, only for our students - there is no limit on attempts to pass certification. In the course we will tell you how to set up special bonus code which will remove restrictions for our students inside the app.

- High concentration of useful material in each lesson

Sometimes you can notice that watching of 5 minutes of our lesson is equivalent to watching of other 30 minutes lesson.

This is because time spent for preparation for the lesson (script for the lesson, lesson structure) and video editing (to cut boring pieces of the lesson, or time when program loads) sometimes 10 times as much (sometimes even 20) as final lesson duration after video editing.

Also each topic is separated from another. In case some concept will be explained in the next lesson and you don't need to worry about understanding this in scope of this lesson - instructor will make announcement when specific topic will be covered.

Course Overview

    This course starts with SOLID Design Principles in Java. It will then provide a comprehensive introduction to Java Design patterns with practical, hands on exercises.

What are SOLID Design Principles?

SOLID design principles are almost a mandatory skill for every Java developer. These principles enable you to write most reusable & clean Java code in your projects.

You'll learn SOLID Principles which are:

Single Responsibility Principle

Open-Closed Principle

Liskov Substitution Principle

Interface Segregation Principle

Dependency Inversion Principle

All these principles are explained in detail and you'll refactor existing Java code and apply these principles in hands on exercise along with me.

Then we move on to Java Design Patterns.

To learn about the design patterns using Java programming language we'll discuss:   

  •     Learn what kind of problems are solved by each design pattern.

  •     Discuss various roles in the design pattern using UML diagrams.

  •     We'll use UML of example that we are going to solve as well as UMLs from gang of four book

  •     Discuss how the design  pattern is applied in the example & how various parts fit together.

  •     Hands on example using Java in Eclipse IDE that uses the design pattern.

  •     Various design & implementation considerations for every design pattern.

  •     Discuss how the design pattern varies from another similar pattern.

  •     See where a design pattern is used in real life.

This course covers all the classic design patterns from the Gang of Four (GoF) book. In addition we'll discuss few newer design patterns that are used in modern software development. We'll discuss how a pattern can be implemented in various ways & how we can tailor them to be used with Java language.

This course is the Most Comprehensive course on Java Design Patterns that you can find.

So, what are Design Patterns & why should you care?

    Design patterns represent solutions to common problems, which you face while doing programming. These solutions are reusable and can solve a wide variety of problems. These became popular with the release of classic book on the subject "Elements of Reusable Object-Oriented Software" writtern by Erich Gamma, John Vlissides, Ralph Johnson and Richard Helm (these authors are known as Gang of Four and so the common abbreviation GoF book :) )
    One problem while studying this book as a Java developer is that the authors are using C++ to demonstrate a pattern, which was the most popular & widely used programming language at the time. So you'll see examples using C++ language features like pointers, copy constructors etc. which do not translate easily to Java.
    This course will help greatly in that aspect. We'll study each design pattern using Java to its full potential.

What is covered in this course?

    This course covers SOLID Design Principles and 26 design patterns in all. We'll cover following:

  • SOLID Design Principles: Learn about Single Responsibility, Open-Closed, Liskov substitution, Interface segregation & Dependency Inversion principles.

  • Creational Design Patterns: Simple Factory, Abstract Factory, Factory Method, Singleton, Builder, Prototype & Object Pool

  • Structural Design Patterns: Object & Class Adapters, Decorator, Bridge, Facade, Static & Dynamic Proxy, Flyweight & Composite  

  • Behavioral Design Patterns: Chain of Responsibility, Command, Interpreter, Mediator, Iterator, Memento, Observer, State, Strategy, Template Method, Visitor, & Null Object

    Each design patterns is also implemented in a follow along coding lecture.

How the Course is Structured?

    We focus on live coding along with theory. Each design is implemented in a live coding session (which you can follow along) as well as discussed with UML & slides. After studing a section you'll know almost everything about the design pattern.

    This course is created with focus on being used as a reference. So each design pattern is discussed in it's own section with a separated lecture for each aspect of the design pattern. Each section is organized as following lectures:
    1. Introduction - This lecture introduces pattern, a problem that it solves & a formal UML diagram
    2. Implementation Steps - This lecture will discuss how you'll implement this pattern in Java.
    3. Example UML - We discuss the UML of the hands on problem we're going to solve.
    4. Implementation - In this lecture we'll implement the design pattern in Java using Eclipse IDE
    5. Implementation & Design Considerations - Some important points about performance, variations & practical advice on using the pattern
    6. Real World Example - In this lecture we'll see how the pattern is used in real life by Java's own class library & popular frameworks like Spring, JSF
    7. Comparison with Similar pattern - See how the pattern is different than another similar pattern.
    8. Pitfalls - Many pattern have some drawbacks. This lecture will show you what those are.
    9. Summary - This lecture will summarise all the information about the pattern.

    As you can see, by breaking a single design pattern in smaller topics, you can easily watch only those parts that you need in future.

What is provided with the Course?

  •  We have provided all code samples from the hands on lectures. You can download the starter code & follow along or you can download the finished code to study on your own.

  •  All UML diagram with description of each role in the design pattern is provided as PDF in summary video. These slides are enough to quickly revise design pattern structure.

  • A PDF guide to all design pattern summaries with code samples and UML diagrams.

Who should take this Course?

  • Beginner as well as experience Developers.

  • Software Designers & Architects.

  • single responsibility principle

  • open closed principle

  • Liskov's substitution principle

  • interface segregation principle

  • dependency inversion principle

  • what is dependency injection?

Section 3 - Creational Design Patterns

  • factory pattern

  • abstract factory pattern

  • builder pattern

  • prototype pattern

Section 2 - Behavioral Design Patterns

  • what are behavioral design patterns?

  • observer pattern

  • command pattern

  • iterator pattern

  • template pattern and null object pattern

  • visitor pattern

Section 3 - Structural Design Patterns

  • decorator pattern

  • flyweight pattern

  • facade pattern

  • adapter pattern

Section 4 - Model-View-Controller (MVC) Pattern

  • the model-view-controller (MVC) model

  • an application with Java Swing

In the first part of the course we are going to learn about the SOLID principles. We are going to talk about the theory as well as the implementations.

The second part of the course is about design patterns. We should have a deep understanding of these patterns in order to be able to write reusable software components. These techniques are becoming more and more important as applications are getting more and more complex, so - in my opinion - these topics are good to know.

Want to create code that is robust, optimized and reusable? Then you need to learn about programmming design patterns.

Game Programming Design Patterns are templates for building modularised code that are generally a repeatable solution to a commonly occurring mechanic applied in computer games. They are general solutions that aren’t tied to a particular problem, making them reusable. One such pattern is object pooling. Whether a game needs an onslaught of constantly spawning zombies or bullets fired from a gun or asteroids to pummel the player’s spaceship, an object pool is a group of classes that can be reused, exactly as they are, across not only these scenarios but a plethora of others whenever game objects need a spawn manager.

In this course, Penny will take you through the top 12 game programming design patterns with C# and the Unity Game Engine using her internationally acclaimed Holistic teaching style and expertise from over 25 years teaching, researching and writing about games. Throughout the course you will follow along with hands-on workshops designed to teach you these core programming concepts that will take your games to the next level.

Learn how to program and work with patterns such as:

  • commands

  • flyweight

  • observer

  • prototype

  • singleton

  • states

  • object pools

  • game loops

  • updates

  • components

  • ...and more.

Contents and Overview

The course begins with a brief introduction and then you are straight into hands-on exercises, working through each of the design patterns as listed above. There are a variety of scenarios you will work on in both 2D and 3D from an asteroid shooter, to a radar object finding system to a programmable prototype prefab system. All starter files and Unity assets (including models and scenes) are provided for you. All you need to bring is a copy of Unity 2019.

If you want to become a knowledgeable and skilled game developer, then this course is for you.

What students are saying about Penny's courses:

  • Excellent course!! I am already in game development industry and there is one quote here from the course that says it all "Whenever you are not able to solve complex problem, its the right time to get back to the BASICS".

  • She is the best teacher ever in this platform

  • I do like Penny de Byl's courses and way of teaching, they are much more specific than your average "master Unity" kind of courses and usually you don't learn just the engine, but also how things work behind the scenes (albeit briefly, at least it gives you an idea if you want to investigate more on your own). She's really amazing!

So you have some Java experience under your belt, but are trying to figure out what to do next to make it easier to get that next job or consulting gig, and to stand out from the crowd.

Maybe you have heard of design patterns before and have seen programmers who know them and are able to implement them are held in very high regard.

One thing is clear, Java programmers with design pattern experience are in high demand.  Design patterns are heavily used in the real world, so it's essential that Java programmers learn how to identify design patterns and implement them.

And that's what you are going to learn in this course!

Perhaps you tried to learn about design patterns in the past, but struggled to understand them.  This course is going to give you the core design patterns experience you need!

This course is unique in comparison to other design patterns courses.

Why?  It not only teaches how to use design patterns, but perhaps more importantly, it teaches why you should use them!  Why they are the best approach and how using them can make you a super productive and awesome Java Programmer.

The reality is that Java developers who truly understand how to use design patterns are in high demand.

So what specifically is included in this course?

This course focuses on the details and a thorough understanding of all design patterns from the Gang of four.

Who are the Gang of four?

Erich Gamma, Richard Helm, Ralph Johnson and John Vlissides released a book in 1994 that was and is still considered a classic.  The concepts are still very relevant in 2019!

This course is all about showing you how to use their design patterns in todays software development environment.

You will learn detailed aspects of common design patterns (23 from the Gang of four) using the Java programming language.

Why should I bother with Design Patterns?

In programming terms, a design pattern is a solution to a common problem that occurs when writing software.  Think of it as more like a template than actual code - its a how-to to solve a problem that can be re-used in many different situations.

Using design patterns gives you a way to solve common problems with a proven solution!  So learning java design patterns and architecture and being able to use and implement them are critical to take your Java programming to new levels.

What you will learn in this course.

You will learn how to implement specific design patterns in addition to learning why they are the best approach and how they make you a super productive and awesome Java programmer.

Many, many examples and challenges are provided to test your understanding of every pattern that you have learned.

This course is unique to other courses here at Udemy in that the details and the why are explained. We do not just go through projects and provide a how-to.  You will learn WHY you should be using a particular design pattern and the benefits to doing so.

Jason Fedin, you instructor is an expert Java developer, and has one of the most popular C programming languages on Udemy (published on this channel).

As a professional programmer, with over 18 years of commercial experience, you can be assured you are learning from a true professional and learning the real-world skills you need to know to succeed.

From 0 to 1: Design Patterns – 24 That Matter – In Java

An intensely practical, deeply thoughtful and quirky look at 24 Design Patterns. Instructors are ex-Google, Stanford.

Students: 7497, Price: $94.99

Students: 7497, Price:  Paid

  • Prerequisites: Basic understanding of Java
  • Taught by a Stanford-educated, ex-Googler, husband-wife team
  • More than 50 real-world examples

This is an intensely practical, deeply thoughtful, and quirky take on 24 Design Patterns that matter.

Let’s parse that.

  • The course is intensely practical, bursting with examples - the more important patterns have 3-6 examples each. More than 50 real-world Java examples in total.
  • The course is deeply thoughtful, and it will coax and cajole you into thinking about the irreducible core of an idea - in the context of other patterns, overall programming idioms and evolution in usage.
  • The course is also quirky. The examples are irreverent. Lots of little touches: repetition, zooming out so we remember the big picture, active learning with plenty of quizzes. There’s also a peppy soundtrack, and art - all shown by studies to improve cognition and recall.
  • Lastly, the patterns matter because each of these 24 is a canonical solution to recurring problems.


What's Covered:

  • Decorator, Factory, Abstract Factory, Strategy, Singleton, Adapter, Facade, Template, Iterator, MVC, Observer, Command, Composite, Builder, Chain of Responsibility, Memento, Visitor, State, Flyweight, Bridge, Mediator, Prototype, Proxy, Double-Checked Locking and Dependency Injection.
  • The only GoF pattern not covered is the Interpreter pattern, which we felt was too specialized and too far from today’s programming idiom; instead we include an increasingly important non-GoF pattern, Dependency Injection.
  • Examples: Java Filestreams, Reflection, XML specification of UIs, Database handlers, Comparators, Document Auto-summarization, Python Iterator classes, Tables and Charts, Threading, Media players, Lambda functions, Menus, Undo/Redo functionality, Animations, SQL Query Builders, Exception handling, Activity Logging, Immutability of Strings, Remote Method Invocation, Serializable and Cloneable, networking.
  • Dependency Inversion, Demeter’s Law, the Open-Closed Principle, loose and tight coupling, the differences between frameworks, libraries and design patterns.

Course Overview

This course provides a comprehensive overview of Design Patterns in JavaScript from a practical perspective. This course in particular covers patterns with the use of:

  • The latest versions of the JavaScript programming language

  • Use of modern programming libraries and frameworks

  • Use of modern developer tools such as JetBrains WebStorm

  • Discussions of pattern variations and alternative approaches

This course provides an overview of all the Gang of Four (GoF) design patterns as outlined in their seminal book, together with modern-day variations, adjustments, discussions of intrinsic use of patterns in the language.

What are Design Patterns?

Design Patterns are reusable solutions to common programming problems. They were popularized with the 1994 book Design Patterns: Elements of Reusable Object-Oriented Software by Erich Gamma, John Vlissides, Ralph Johnson and Richard Helm (who are commonly known as a Gang of Four, hence the GoF acronym).

The original book GoF book used C++ and Smalltalk for its examples, but, since then, design patterns have been adapted to every programming language imaginable: C#, Java, Swift, Python and now — JavaScript!

The appeal of design patterns is immortal: we see them in libraries, some of them are intrinsic in programming languages, and you probably use them on a daily basis even if you don't realize they are there.

What Patterns Does This Course Cover?

This course covers all the GoF design patterns. In fact, here's the full list of what is covered:

  • SOLID Design Principles: Single Responsibility Principle, Open-Closed Principle, Liskov Substitution Principle, Interface Segregation Principle and Dependency Inversion Principle

  • Creational Design Patterns: Builder, Factories (Factory Method and Abstract Factory), Prototype and Singleton

  • Structrural Design Patterns: Adapter, Bridge, Composite, Decorator, Façade, Flyweight and Proxy

  • Behavioral Design Patterns: Chain of Responsibility, Command, Interpreter, Iterator, Mediator, Memento, Observer, State, Strategy, Template Method and Visitor

Who Is the Course For?

This course is for JavaScript developers who want to see not just textbook examples of design patterns, but also the different variations and tricks that can be applied to implement design patterns in a modern way. For example, the use of Symbol.iterator allows objects (including iterator objects) to be iterable and lets scalar objects masquerade as if they were collections.

Presentation Style

This course is presented as a (very large) series of live demonstrations being done in JetBrains WebStorm and presented using the Kinetica rendering engine. Kinetica removes the visual clutter of the IDE, making you focus on code, which is rendered perfectly, whether you are watching the course on a big screen or a mobile phone. 

Most demos are single-file, so you can download the file attached to the lesson and run it in WebStorm, Atom or another IDE of your choice (or just run them from the command-line).

This course does not use UML class diagrams; all of demos are done via live coding.

Design patterns provide a vocabulary to discuss problems and solutions with a common context. They are used in Object Orientated Programs. They’re the recipe or instructions, and once you’ve read them, you’ll be able to more easily follow any piece of code that uses them.

Many software developers first encounter design patterns when they study computer science in college or at university. This typically happens in the second year, after students learn about object-oriented programming and related topics such as inheritance, encapsulation, and polymorphism.

This is a good time to start learning about patterns because it will help you to get more out of the rest of your coursework.

However, not all professional developers learn about design patterns in their formal education. Some don't have the opportunity to learn about patterns at all. The experience of many developers is that design patterns emerge from on-the-job training and experience with projects of increasing size and complexity.

In this course we explain Object Orientated Design Patterns with Python through examples. It includes the factory method, command pattern and many others. All Python source code is included in the course so you can study at your own pace, the videos explain them in more details.

This course begins with examination of a realistic application, which is poorly factored and doesn't incorporate design patterns. The demo application converts text into subtitles for videos, which makes it quite useful in practice. Yet, it is nearly impossible to maintain and develop this application further, due to its poor structure and design.

That is the point at which the course begins. As demonstration after demonstration will unfold, we will refactor this entire application, one function and one class at a time. During refactoring, many design patterns will fit into place almost without effort. By the end of the course, you will know how code refactoring and design patterns - one coding practice and one design practice - can operate together and help each other create great design.

The best way to learn design pattern is by doing a project. If you learn something with a project you learn quickly and you learn to the point. So in this training series we have started with 10 labs which completes a customer data entry screen and implements some important patterns like Factory , Repository , Unit of work , Decorator , Iterator , Mediator and so on.

One of the shortcomings of learning with a project is you can not implement all design patterns in one project. So to cover them i have also created individual videos for each design pattern. These specific videos goes more in-depth in to those individual design pattern videos.

In this syllabus i have also stressed on architectural concepts like DI , IOC , SOLID principles , Micro services architecture and so on.

Below is a the full syllabus of this course :-
Lab 1: - Project kick start with requirement , planning and initial coding(Factory pattern,Lazy Pattern and RIP Pattern).
Lab 2: - Unity,  Strategy, IOC, SRP and SOC.
Lab 3: - Template pattern and Repository pattern with ADO.NET.
Lab 4: - Adapter Pattern and Repository with EF
Lab 5: - UOW(Unit of Work)
Lab 6: - Decorator Pattern
Lab 7: - Iterator Pattern
Lab 8: - Prototype and Memento Pattern
Lab 9: - Implementing complex object creation using Factory Method
Lab 10: - Implementing NULL design pattern and Mediator pattern.
Explain SOLID?
Factory pattern and Abstract Factory Pattern

Best in class course if your objective is to build a Solid Foundation on OOPs and get your basics strong.

This course Course Object Oriented Programming & Design in Java is created with a clear objective in mind to build a solid foundation in Object Oriented Programming.

Because Solid and Strong Basics can lead to solve any programming problem! and help to write more elegant Machine and Human friendly code.

Object Oriented programming is there for quite a while now but we found that the course covers either only programming syntax and concepts of OOPs or Design Principl and patterns.

It is essential that when you start learning OOPs you should also learn many other related things like Design Principles, Object oriented design and Design Patterns as well because without learning these concepts your knowledge portfolio for OOPs is not complete.

So we bring to you this course where we will not only cover Object Oriented Programming concepts in Java but also Design Patterns, and Design principles along with best practices and OOPs philosophy.

This course also have sections where we will discuss about OOPs philosophy that will improve your thinking in Object oriented world.We have also created a small section on UML where we will discuss mainly class diagram and Sequence diagram that will help us learning design patterns.

Outline of what we have covered in this course

Prerequisites to Learn OOPs

  • Classes, Objects

  • Variables-Methods-constructors

  • packages, import keyword

  • Access Modifiers

  • Non-Access Modifiers

You may skip this section if you already know these concepts. After completing the same as we will be prepared to start the Journey. We will start discussing the actual OO concepts

OOPs Concepts

  • Data Hiding

  • Interfaces and Abstract class

  • Abstraction

  • Encapsulation

  • Inheritance - ISA relationship

  • Types of inheritance

  • Association with concepts of aggregation

  • HAS-A Relationship and composition

  • Polymorphism - Overloading and overriding

This section will cover the basics of OOPs concept related to Java and in general.

In Next section of the course we will Quickly discuss some philosophical Angles of OOPs to improve your thinking in Object Oriented world. This section will not have

much of a coding but will after completing this you will certainly feel more confident and connected to Object Oriented World.

After you start thinking clearly in OOPs we will start some of the very Important Design Principles in OOPs. These principles are the De Facto standard for object Oriented design for several years.

Design Principles

  • SOLID principles

  • DRY

  • KISS

  • YAGNI

  • SLAP

After completing this section you will be very confident and artistic in Object oriented programming.

After completing this we will have a section on Quick UML where we will discuss Class and Sequence Diagram because that is necessary to learn Design Patterns

UML

  • Class Digram

  • Sequence Daigram

We will use a lot of Sequence diagram and Class diagram in while discussing Design Patterns.Then we will come to a very popular topic in OOPs world and that is Design Patterns.We will discuss all 23 GOF design Patterns with the help of UML Code and Sequence diagram.

      Creational Design Patterns

  • Prototype Design Pattern

  • Builder Design Pattern

  • Singleton Design Pattern

  • Factory Method

  • Abstract Factory Design Pattern

    Behavioural Design Patterns

  • Chain Of Responsibility Pattern

  • Command Design Pattern

  • Interpreter Design Pattern

  • Iterator Design Pattern

  • Mediator Design Pattern

  • Memento Design Pattern

  • Observer Design Pattern

  • State Design Pattern

  • Strategy Design Pattern

  • Template Design Pattern

  • Proxy Design Pattern

After completing this we will discuss some of the coding best practices

Best practices.

  • Technical Debt

  • High Cohesion

  • Loose Coupling

  • Primitive Obsession - Code smell

  • Comment why not what

Hope this should be enough for you to become comfortable in Object Oriented programming and design in Java.

We have crafted the content, code examples and all other stuff in a way so that by end of this complete course you start feeling extremely comfortable and Confident in Programming OOPs.

So I am excited to welcome you again to this course hope we will have a very fruitful Journey with a clear objective to learn OOPs and OOPs design.

All the Best in building a SOLID foundation.

This course come with a 30 Days Money back guarantee so do't worry if it does not fit into your needs.

Welcome Again! and Happy Learning

Design Patterns are repeatable and reusable solutions for software design related issues.

This course helps you to get introduced to the some of the frequently used Design Patterns among Software developers and demo how we can use them in Test Automation to achieve better re-usability and maintainability in the your Automation Framework, Page Objects & Test classes design!

You would learn following Design Principles and Design Patterns.

  • Single Responsibility Principle: Each and every module, class, method in an application should have only one specific responsibility to handle. Using this we could refactor our complex Pages Objects into multiple modular Page Components or Page Fragments and we could write very neat test steps.

  • Factory Pattern: We should be able to create an object without exposing the creation logic to the test class. For ex: Lets consider the localization testing in which we need to test multiple languages for an app. This app might have a language specific behavior as well. We can have an abstract class with common functionalities and language specific sub classes. We can use Factory Pattern to create specific Page Object based on the language we test!

  • Strategy Pattern: We should be be able to pass the behavior to an object at run time. For ex: Google search page might have different search strategies. Text based search or voice based search. We have a Page Object for google search page and different components for search strategies. We should be able to pass specific strategy at run time w/o writing ugly if-else blocks.

  • Command Pattern: An object is encapsulated with all the information required to run this at a later stage when required. It would be very useful for a Page with multiple UI components with a lots of UI validations.

  • Template Method Pattern: A super class defines a high-level steps/skeleton and all the sub classes override the steps. For ex: An application for room booking and car booking will have similar workflow but with different options. This Pattern explains how to create better Page Objects using this pattern.

  • Proxy Pattern: A placeholder object for another object. For ex: You want to execute some steps on QA environment and want to skip same steps on PROD environment because we might not be allowed to execute those steps. This pattern helps you to write such cases in a much better way.

  • Execute Around Method Pattern: Sometimes we might have to do some steps always. For ex: To read a file, open a file, read and close. To write content into a file, open a file, write and close. If you see, opening and closing file steps are common and should be done always irrespective of reading or writing content into a file.  This pattern explains how to write such steps in a better way.

  • Decorator Pattern: Some times an application will have different UI components depends on the user role. An admin role will have all the access. A user role will have limited access etc. How to create such page objects based on user roles. This is what this pattern is about.

Launched in 2020 and continually updating our course content to expand our curriculum! Welcome to our Design Patterns & SOLID Principles course, developed with Java programmers in mind! Our course will help you understand and discover the Design Patterns created by the Gang of Four (Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides) who wrote the book "Design Patterns: Elements of Reusable Object-Oriented Software".
Design Patterns are general solutions to problems that appear over and over again in complex applications. Whether you are familiar with the topic and need a recap, or are starting your programming studies, this course is for you. With a brilliant look at the theory of this topic, the course also brings a practical element into it whereby you can test your own programming skills through our Eclipse projects. Understanding Design Patterns gives you a broad catalogue of general solutions to tackle even the most complicated programming tasks, which have been discovered, analysed and described in detail by the Gang of Four in their book.

What are Design Patterns?
Design Patterns are identified as 23 general, repeatable solutions to problems that we are likely to come across as a programmer and were developed by the infamous Gang of Four. They are divided into 3 main categories: creational, structural and behavioural. We take a look at each of these patterns and explain them in an easy to follow manner, explaining how they can be used to elegantly solve problems while complying with the requirements of encapsulation, extensibility and other factors that a professional design requires.

What are SOLID Principles?
SOLID Principles are perhaps the best-known set of principles to assess the quality of an object-oriented system. They help us detect bad smells in our code and create clean architectures. Examples of these principles include the Open / Closed Principle and the Liskov Substitution Principle. This course will highlight to you what a beautiful and essential part of programming they are. Hoping they come in handy and change your perception even of your work.

Our course program:
Each of our lessons takes you through the theory of a pattern or principle with concise and clear explanations, getting straight to the point. We have created practical exercises via 18 Eclipse projects for you to test your understanding, which comes with an automated correction system. Internalizing the theory through these exercises is fundamental to learning and improving our code writing skills. As well as this, at the end of each section, there is a short quiz for quick-fire checking of your knowledge!

As our students come from all over the world, we have developed subtitles in both English and Spanish to assist with the learning experience. We intend to give our students the best support they can get while taking our course; therefore, we are always on hand to answer any questions via the Q&A tab and message board.

Summary of what our course includes:
- Easy to follow presentations covering Design Patterns & SOLID Principles
- Downloadable PDF of the presentation
- Practical exercises via Eclipse projects with an automated correction system
- End of section quiz
- Subtitles in English (UK & US) and Spanish

If you've been looking for an opportunity to improve your code-writing skills, this is the right course for you!

Design Patterns in C# Made Simple

More than two decades since design patterns have appeared, many developers consider them the most important discovery in software development. Others still find them a bad idea. And both are right! How comes?

In this course, you will learn how design patterns can be applied to make code better: flexible, short, readable. Flexibility is the key element in design patterns. You will learn how to decide when and which pattern to apply by formally analyzing the need to flex around specific axis. You will learn which pattern is adding which kind of flexibility, and what are the most common forms of implementation in practice. You will also learn common pitfalls and ways to overcome them when applying specific patterns.

Through a series of demonstrations, you will learn one design pattern at a time. In each demonstration, we shall start from an existing implementation which faces difficulties to accommodate the next requirement proposed by the customer. That will invariantly trigger a series of designing attempts, some doomed to fail, others having prospect to succeed. But what will learn in this course, is that each successful design will exhibit one kind of flexibility, which will be of critical importance to support the troublesome request posed by the customer. It will come as no surprise to you to learn that each such special kind of flexibility will be one specific design pattern.
