You’ve just stumbled upon the most complete, in-depth Java programming course online. With close to 600,000 students enrolled and over one hundred and forty thousand reviews (with tens of thousands of those 5-star) to date, these comprehensive java tutorials cover everything you’ll ever need.

Whether you want to:

- build the skills you need to get your first Java programming job

- move to a more senior software developer position

- pass the oracle java certification exam

- or just learn java to be able to create your own java apps quickly.

...this complete Java Masterclass is the course you need to do all of this, and more.

N.B. Java 17 support coming soon, read on below...

Are you aiming to get your first Java Programming job but struggling to find out what skills employers want and which course will give you those skills?

This course is designed to give you the Java skills you need to get a job as a Java developer.  By the end of the course, you will understand Java extremely well and be able to build your own Java apps and be productive as a software developer.

Lots of students have been successful in getting their first job or promotion after going through the course.

Here is just one example of a student who lost her job and despite having never coded in her life previously, got a full-time software developer position in just a few months after starting this course.  She didn't even complete the course!

"Three months ago I lost my job, came to a turning point in my life, and finally made the drastic decision to completely change course.   I decided to switch career paths and go into coding. My husband found and gave me your Complete Java Masterclass at Udemy as a gift, and I wholeheartedly dove into it as a lifeline. Following your course has been absolutely enjoyable (still working on it, not yet finished), and has been a great way of keeping on course, dedicated and motivated.  Yesterday, three months after starting the course, and honestly to my surprise, I received (and accepted!) a job offer as a full-time developer. I wanted to just drop you a line to say thank you for doing this work, for being such a dedicated teacher, and for putting all this knowledge available out there in such an approachable way. It has, literally, been life-changing. With gratitude,  Laura"

The course is a whopping 80 hours long.  Perhaps you have looked at the size of the course and are feeling a little overwhelmed at the prospect of finding time to complete it.   Maybe you are wondering if you need to go through it all?

Firstly, Laura's story above shows that you do not have to complete the entire course - she was yet to complete the course when she accepted her developer job offer.

Secondly, the course is designed as a one-stop shop for Java.

The core java material you need to learn java development is covered in the first seven sections (around 14 hours in total).  The Java Basics are covered in those sections. The rest of the course covers intermediate, advanced, and optional material you do not technically need to go through.

For example section 13 is a whopping 10 hours just by itself and is aimed at those students who want to build desktop applications with graphical user interfaces.  JavaFX (which is the technology used in this section) is something that most java developers will rarely or never need to work on.  So you could skip that section entirely.  But if you are one of the few that need to build user interfaces, then the content is there and ready for you.   And there are other sections you can completely avoid if you wish.

If you want to know absolutely everything about Java, then you can go through the entire course if you wish, but it's not necessary to do so if you are just looking to learn the essential information to get a java developer position.

Why would you choose to learn Java?

The reality is that there is a lot of computer languages out there.  It's in the hundreds.  Why would you choose the Java language?

The number one reason is its popularity.  According to many official websites that track the popularity of languages, Java is either #1 or in the top 3.  Popularity means more companies and their staff are using it, so there are more career opportunities available for you if you are skilled in the language.

The last thing you want to do is pick a language that is not in mainstream use.  Java came out in the 1990s and is still very popular today.

What version of Java should you learn?

Generally speaking, you would want to learn the very latest version of a computer programming language, but that's not the case with Java.

Oracle, the owner of Java release many versions of Java.  Some are released and expire in six months, with no future updates or support.  Other versions have long-term support, for many years.

You can probably see why learning a version of Java that has expired makes no sense, and is likely a waste of time.

A company using Java technology (big or small) is not going to use a version of Java that has no updates or support.  They will stick to stable, well-supported versions of Java that get updates.

Right now, in July 21 the version of Java that offers this long-term support (LTS) is Java 11 - It's being fully supported until at least 2025 and likely will be extended from there.

As such, you want to learn the version of Java that your future employer will use, and that's Java 11.

The next LTS version of Java is Java 17, scheduled for release in September 2021.   The course will be updated, and the updates made available to you free once Java 17 is live.  The course will also be updated in the future as new LTS versions are announced by Oracle.

BOTTOM LINE: You will learn the RIGHT VERSION of JAVA in this course!  Right meaning the right version to maximize your future Java potential with clients or Employers.

Will this course give me core java skills?

Yes, it will.  Core Java is the fundamental part of the Java JDK (the java development kit) that programmers need to learn to move onto other more advanced technologies.

Why should you take this course?

It's been a best-seller since its release on Udemy, you would be joining close to 600,000 students who are already enrolled in the course.

There are well over 140,000 reviews left by students.  It's rated as the best course to learn Java for beginners.

What makes this course a bestseller?

Like you, thousands of others were frustrated and fed up with fragmented Youtube tutorials or incomplete or outdated courses which assume you already know a bunch of stuff, as well as thick, college-like textbooks able to send even the most caffeine-fuelled coder to sleep.

Like you, they were tired of low-quality lessons, poorly explained topics, and confusing info presented in the wrong way. That’s why so many find success in this complete Java developer course. It’s designed with simplicity and seamless progression in mind through its content.

This course assumes no previous coding experience and takes you from absolute beginner core concepts, like showing you the free tools you need to download and install, to writing your very first Java program.  You will learn the core java skills you need to become employable in around 14 hours, and if you choose to, can take advantage of all the additional content in the course. It's a one-stop shop to learn java. If you want to go beyond the core content you can do so at any time.

Here’s just some of what you’ll learn

(It’s okay if you don’t understand all this yet, you will in the course)

  • All the essential Java keywords, operators, statements, and expressions needed to fully understand exactly what you’re coding and why - making programming easy to grasp and less frustrating

  • You will learn the answers to questions like What is a Java class, What is polymorphism and inheritance and to apply them to your java apps.

  • How to safely download and install all necessary coding tools with less time and no frustrating installations or setups

  • Complete chapters on object-oriented programming and many aspects of the Java API (the protocols and tools for building applications) so you can code for all platforms and derestrict your program’s user base (and potential sales)

  • How to develop powerful Java applications using one of the most powerful Integrated Development Environments on the market, IntelliJ IDEA! - Meaning you can code functional programs easier.  IntelliJ has both a FREE and PAID version, and you can use either in this course.

(Don’t worry if you’re used to using Eclipse, NetBeans, or some other IDE. You’re free to use any IDE and still get the most out of this course)

  • Learn Java to a sufficient level to be a be to transition to core Java technologies like Android development, the Spring framework, Java EE (Enterprise edition) in general as well as and other technologies. In order to progress to these technologies, you need to first learn core Java - the fundamental building blocks.  That's what this course will help you to achieve.

“AP-what?”

Don't worry if none of that made sense. I go into great detail explaining each and every core concept, programming term, and buzzwords you need to create your own Java programs.

This truly is Java for complete beginners.

By the end of this comprehensive course, you’ll master Java programming no matter what level of experience you’re at right now. You’ll understand what you are doing, and why you are doing it. This isn’t a recipe book, you’ll use your own creativity to make unique, intuitive programs.

Not only do these HD videos show you how to become a programmer in great detail, but this course includes a unique challenge feature. Each time a core concept is taught, a video presents a challenge for you to help you understand what you have just learned in a real-world scenario.

You’ll go and complete the challenge on your own, then come back and see the answers which I then explain in detail in a video, allowing you to check your results and identify any areas you need to go back and work on.

This is a proven way to help you understand Java faster and ensure you reach your goal of becoming a Java Developer in record time. Remember doing those old past exam papers in high school or college? It’s the same concept, and it works.

As your instructor, I have close to  40 years of experience as a software developer and teacher and have been using Java since the year 2000. Yes, over 21 years (I’ve taught students younger than that). Meaning not only can I teach this content with great simplicity, but I can make it fun too!

It’s no surprise my previous students have amazing results...

See what your fellow students have to say:

"This course was a guiding light in my "Becoming a developer" path from the first step. It helped me become a much more educated developer comparing to my friend who learned to code from trial/error. It's still a guide for me. every now and then I will come back to this course to learn something new or to improve what I've learned somewhere else. A BIG Thanks to "Tim Buchalka" my Master." - Sina Jz

"I was an absolute beginner when I started this course, and now I can write some good small advanced clean codes. I wrote a code and showed it to a programmer, and he was shocked, he told me that I'm more than ready to start a programming career." - Amirreza Moeini

"I am taking this class in conjunction with a Java 101 college class. I have learned more in one afternoon of videos from this class than I have in 4 weeks of a college class. Tim actually explains what things are and why they do what they do, as opposed to my college instructor that mainly said "go make a program that does *whatever*" and then I had to figure out a program that would meet those requirements but not actually learning why it worked." - Stacy Harris

It’s safe to say my students are thrilled with this course, and more importantly, their results, and you can be too

This complete Java course will teach you everything you need to know in order to code awesome, profitable projects,

Is the course updated?

It’s no secret how technology is advancing at a rapid rate. New, more powerful hardware and software are being released every day, meaning it’s crucial to stay on top with the latest knowledge.

A lot of other courses on Udemy get released once, and never get updated.  Learning an older version of Java can be counterproductive - you could be learning the "old way" of doing things, rather than using current technology.

Make sure you check the last updated date on the page of any course you plan to buy - you will be shocked to see some have not been updated for years. 

That’s why I’m always adding new, up-to-date content to this course at no extra charge. Buy this course once, and you’ll have lifetime access to it and any future updates (which are on the way as we speak).

I've continued to do this since the original version of the course came out, and recently have been updating it to Java 11.  And again, once Java 17 is live, I'll be on the update trail again, to Java 17.

With this complete Java Masterclass, you will always have updated, relevant content.

What if I have questions?

As if this course wasn’t complete enough, I offer full support, answering any questions you have 7 days a week (whereas many instructors answer just once per week, or not at all).

This means you’ll never find yourself stuck on one lesson for days on end. With my hand-holding guidance, you’ll progress smoothly through this course without any major roadblocks.

Student Quote: “This course is a great place to ask questions if you have them or find help if you become stuck in areas.” - Blake S.

There’s no risk either!

This course comes with a full 30-day money-back guarantee. Meaning if you are not completely satisfied with the course or your progress, simply let me know and I’ll refund you 100%, every last penny no questions asked.

You either end up with Java skills, go on to develop great programs and potentially make an awesome career for yourself, or you try the course and simply get all your money back if you don’t like it…

You literally can’t lose.

LAST UPDATED: November 2020

  - Latest updates include Lambdas and Streams with Java 9 Features.

Welcome to Master Practical Java Development.  This course is designed to help you master the most in-demand and critical components for becoming a Core Java developer. Especially if you're going for a job interview or have a Java Project that needs your best performance. This course assumes no prior java experience so  prior Java so it will take you from zero to hero!

The topics covered include Object Orientation which I think is not stressed enough in other Java courses so I've got special focus on that throughout the lectures. You'll get plenty of practice writing classes and interfaces as well as countless methods with loops and if else statements, exception handling and file processing as well as how to debug software using Eclipse. You'll also be mastering the collections framework and diving deep into java generics. You'll learn all there is to know about multi-threading and the JDBC API for working with a MySQL database. There are also practical projects scattered throughout the course so that you can practice the concepts as you learn them. For example one of the projects is related to a car dealership management system and another assignment involves processing files with stock market data. So as you can see, I tried to keep the projects professional and industry relevant rather than cloning a game like flappy bird.

I want this course to be the ultimate go-to resource for anyone that's looking to become a core Java programmer so I intend on adding more content to this course based on new technologies and student feedback. The content is Java 9 ready which means I'll show you how to upgrade to the latest version of Java which is version 9 and I'll teach you how to configure Eclipse to work with both Java 8 as well as version 9.

Don’t just take it from me, take it from other students that have taken this course.

★★★★★ Here’s reviews from real students that took this course ★★★★★

★★★★★ Instructions are very clear and easy to follow. I know nothing about java and so far I’m keeping up just fine.

★★★★★ Easy to understand the difficult topics as well. Overall nice course. Learnt the basic java concepts very well and also collections framework and JDBC topics are also very nicely explained.

★★★★★ The explanation of each concept is done very well. This is a great course for beginners.

★★★★★ This course is awesome! The teacher is very thorough with his explanations of the theory and application. I'm really enjoying it!

★★★★★ Yes it is for sure the best!! As it covers all the topic from basic to advanced topics in java.

★★★★★ I am taking my second semester of Java programming at university. I signed up for this course to augment my university studies. I learn more from this one course with a better understanding of programming principles than I have learned at university.The university gives me college credit; this course will get me a job!

★★★★★ I'm taking a class about object-oriented programming in relation to Java. However, the reading material uses quite a bit of technical lengthy jargon that I simply get confused. This class has been extremely helpful in presenting concepts in a straightforward and simple way. I can understand what he's explaining and it makes sense. This is a fantastic course and I'd recommend it to anyone who is feeling discouraged about learning about object-oriented programming.

★★★★★ Congratulations – the instructor has turned complicated topics into easy interactive components. High praises to the instructor are in order. The instructor was very knowledgeable, worked at a good pace, and most importantly, was very good at communicating.

Hi!

This course is designed for students or anyone else who want to start Java as a programming language. We will consider several topics ranging from installing Java itself to MySQL database operations. The first chapter will be about the basics: loops, decision making, variables and so on. The next chapters will be about exception handling as well as how to deal with input/output operations. Of course, we will consider the object orinted principles: inheritance, polymorphism and encapsulation as well. The last chapter will be about how to connect to a MySQL database and how to make the basic database-related operations: inserting new items, removing items or updating items in the database table.

This is a very rapid course on Java 8 functional programming.

Functional programming has been the most important of all Java 8 new features. Using Java 8 functional programming, we can now code many things much faster than before, in a concisefluent and readable manner. But, unless you learn those functional programming features properly, getting used to those becomes a bit confusing. So, in this course, we are going to grasp how to do functional programming in an intuitive and conceptual manner, very rapidly. We'll learn each feature with simple and crisp examples, which'll be very brief but quite informative.

This course is actually part I of a two-part course. It covers about Java Lambdas, e.g. lambda expressions, method references, composing lambda expressions etc. The next part, which is coming soon, will be about Streams. You'll find link to that in the resources section of the last lesson.

We've done some practical exercises in the lessons here, and the links to the source codes are available in the resources section.

What is Java?

Java is a concurrent, compiled, object-oriented programming language. It was created in 1995 by Sun Microsystems (now Oracle) and can be found across many websites, applications, and programs. It was modelled after C++, but intended to be simpler and easier to use.

Java must be run on a software platform, such as the Java Platform by Oracle or the Android SDK for mobile devices. Java is commonly used in Android apps, enterprise software, financial and scientific software, big data calculations, and web applications.

JavaScript is a high-level programming language, which is one of three core technologies of World Wide Web content production. It can be used to make web pages interactive and provide online programs, such as video games. It is widely used, and is employed by the majority of websites and is supported by all modern web browsers. As you can see, if your hoping for a career in programming or web development then this course will be extremely beneficial, and could help you get the career you want.

Why learn Java?

Java is one of the most popular programming languages out there, mainly because of how versatile and compatible it is. Java can be used for a large number of things, including software development, mobile applications, and large systems development. As of 2019, 88% market share of all smartphones run on Android, the mobile operating system written in Java. Knowing Java opens a great deal of doors for you as a developer.

Who learns Java?

Mobile app developers, web developers, and software engineers might need to know Java to create and maintain their products. Java is less intuitive and more complex than other web development languages like Python, so it’s better to start elsewhere if you’re new to programming.

What version of Java should you learn?

Generally speaking you would want to learn the very latest version of a computer programming language, but thats not necessarily the case with Java.

Until recently Java releases were infrequent (one major release in 3 years was common). Companies standardised on specific versions of Java. Right now most companies are still focused on Java 8, which is a relatively old version, dating back to 2015.

Oracle (the owners of Java) are now releasing new versions of Java every six months, and when the new version comes out the old version is no longer supported.

But to cater for most companies who tend to stick to specific versions of Java for a long time, they have marked the current version of Java - Java 11 as LTS - or Long Term support. That means that they guarantee to support this version for the long term - for a number of years at least.

Companies will stick to versions of Java that are supported in the long term. For career purposes you should learn the appropriate versions of Java that your future employer will likely be using. Right now thats Java 8 and Java 11 (Java 9 and Java 10 have been released and already been marked obsolete and are no longer supported).

Job Prospects

According to PayScale, the average salary for a Java developer is $69,722 per year, with an average salary range of $47,169 to $106,610 per year. The highest-paid Java developers are in San Francisco and Arlington, where the average reported yearly salaries are $97,000 per year.

A Servlet is a Java Programming language class that is used to extend the capabilities of servers that host applications accessed by means of a request-response programming model. Although servlets can respond to any type of request, they are commonly used to extend the applications hosted by web servers. It is also a web component that is deployed on the server to create a dynamic web page.

Servlet Technology resides at server side and it generates dynamic web page, used to create web application. Java Servlets are programs that act as a middle layer between a requests coming from a Web browser / HTTP client and databases or the applications on the HTTP server.

Servlet is a Java class that runs inside the container. It allows you to process the HTTP request and generate dynamic web pages, but it's more Java then HTML like you need to code HTML inside Java, which is both erroneous and not recommended. Servlet is mainly used as a Controller in web applications created using the MVC design pattern. One of the famous examples of that is the DispatcherServlet of Spring MVC framework, which acts as a front controller. Its job is to receive request and process it, but the view generate or dynamic web page generation functionality is passed down to JSP. Though it provides the data that need to be shown in JSP, which makes the view part of the Model View Controller (MVC) design pattern.

Before servlets, we had CGI i.e. Common Gateway Interface. It is a standard way for a Web server to pass a user’s request to an application program and receives the response to forward to the user. When the user requests a Web page, the server sends back the requested page. However, when a user fills out a form on a Web page and sends it in, it is processed by an application program. The Web server typically passes the form information to a small application program. This program processes the data and sends back a confirmation message. This process of passing data back and forth between the server and the application is called the common gateway interface (CGI). It is part of the Web’s Hypertext Transfer Protocol.

This practical, application-oriented Java Servlets training by Uplatz teaches Java Servlets technology and shows how to use it to develop simple to complex web applications. It is intended for both the beginners as well as experienced Java (J2SE) programmers who want to build web applications or J2EE components and systems.

The Java Servlet course begins with an overview of server-side Java programming and web protocols. Then students learn the Java Servlets architecture, the request/response cycle, and servlet life cycle, and how to build interactive web applications that parse and/or generate HTML forms. Several prominent patterns for servlet application architecture are considered. Sessions are studied as a means to developing sophisticated client/server conversations over several HTML pages. Multi-tier applications are developed using servlets and JDBC for access to relational databases.

This Java Servlet training develops the important concept of the separation of programmatic and declarative development: use of configuration and context information in lieu of hard-coded values, resource locations, etc., to make the web application as portable and easy to administer as possible. The course introduces JavaBeans as a standard for business and data objects that can be shared among servlets and JSPs, and develops techniques for sharing such objects at session scope or by request forwarding. Finally, students learn how to implement filters to adapt existing servlets by pre- and post-processing the request and response.

  • Write servlets using the Java programming language (Java servlets)

Java Servlets: Servlet Architecture

The Java Servlet architecture includes communication interface, protocol used, requirements of client and server, the programming with the languages and software involved. Basically, it performs the below-mentioned tasks.

  • First, it reads the explicit data sent by the clients (browsers). This data can include an HTML form on a Web page, an applet or a custom HTTP client program. It also reads implicit HTTP request data sent by the clients (browsers). This can include cookies, media types and compression schemes the browser understands, and so forth.

  • After that, the servlet processes the data and generate the results. This process may require communicating to a database, executing an RMI, invoking a Web service, or computing the response directly.

  • After processing, it sends the explicit data (i.e., the document) to the clients (browsers). This document can be sent in a variety of formats, including text (HTML or XML), binary (GIF images), or Excel formats.

  • Finally, it also sends the implicit HTTP response to the clients (browsers). This includes telling the browsers or other clients what type of document is being returned

Servlet Life Cycle

The Servlet life cycle mainly includes the following four stages,

  • Loading a Servlet

  • Initializing the Servlet

  • Request handling

  • Destroying the Servlet

Java Servlets: Steps to Create Servlet

  1. Create a directory structure

  2. Create a Servlet

  3. Compile the Servlet

  4. Add mappings to the web.xml file

  5. Start the server and deploy the project

  6. Access the servlet
