Object Oriented Programming (OOPs) Concepts in English

Learn all the concepts of OOPs (Object Oriented Programming)

Created by RAKESH P - Software Developer


Students: 7445, Price: Free

Object Oriented programming is a programming style that is associated with the concept of Class, Objects and various other concepts revolving around these two, like Inheritance, Polymorphism, Abstraction, Encapsulation etc.

Object means a real word entity such as pen, chair, table etc. Object-Oriented Programming is a methodology or paradigm to design a program using classes and objects. It simplifies the software development and maintenance by providing some concepts:

  • Object

  • Class

  • Inheritance

  • Polymorphism

  • Abstraction

  • Encapsulation


Any entity that has state and behavior is known as an object. For example: chair, pen, table, keyboard, bike etc. It can be physical and logical.


Collection of objects is called class. It is a logical entity.


When one object acquires all the properties and behaviours of parent object i.e. known as inheritance. It provides code reusability. It is used to achieve runtime polymorphism.


When one task is performed by different ways i.e. known as polymorphism. For example: to convince the customer differently, to draw something e.g. shape or rectangle etc.


Hiding internal details and showing functionality is known as abstraction. For example: phone call, we don't know the internal processing.

How is this course structured?

  1. I will teach you in a hierarchical way from the basic to advance level.

  2. There is a video lecture on every topic explained in English.

Who is the target audience?

  1. An Absolute beginner who want to learn OOPs from scratch.

About JavaScript (Wiki):

JavaScript often abbreviated as JS, is a programming language that conforms to the ECMAScript specification. JavaScript is high-level, often just-in-time compiled, and multi-paradigm. It has curly-bracket syntax, dynamic typing, prototype-based object-orientation, and first-class functions.

Alongside HTML and CSS, JavaScript is one of the core technologies of the World Wide Web. JavaScript enables interactive web pages and is an essential part of web applications. The vast majority of websites use it for client-side page behavior, and all major web browsers have a dedicated JavaScript engine to execute it.

As a multi-paradigm language, JavaScript supports event-driven, functional, and imperative programming styles. It has application programming interfaces (APIs) for working with text, dates, regular expressions, standard data structures, and the Document Object Model (DOM).

An Introductory Course to Object Oriented Programming

Object Oriented Programming

Created by Suruchi Malao - Professional Tutor


Students: 512, Price: Free

Now a days, software engineers and industry are forced to continuously look for new approaches to software design and development. Object Oriented Programming provides a solution to problems faced during design phase of software development.

Object Oriented Programming helps to address following issues of software development:

  • Represent real-life entities of problems in system design

  • Design systems with open interfaces

  • Ensure re-usability and extensibility of modules

  • Support software version management

  • Decrease software cost and improve software productivity

  • Improve software quality

  • Industrialize the software development process

Object Oriented Programming incorporates best features of structural programming features with several powerful new concepts; this eliminates some of the pitfalls of conventional programming methods.

Programming Paradigms defines how the structure and basic elements of a computer program will be built. Programming Paradigms is a set of capabilities and limitations of a programming language. The course starts with an overview of traditional programming paradigms such as Monolithic Programming , Procedural programming and Structural Programming in the first sections with advantages and disadvantages of all programming paradigms. In the next session the course proceeds with the introduction to Object Oriented Programming Paradigms and its advantages. Python is a multi-paradigm programming language which also supports Object Oriented Programming. The course ends with explanation of Classes and Object of Object Oriented Programming using Python programming language

Features of Object oriented Programming language

Major features of OOP

Created by Vaishali Rajeev Lele - Assistant Professor


Students: 245, Price: Free

Nowadays, Object oriented Programming (OOP) languages are popularly used for software development. OOP languages include C++, Java. OOP languages are very helpful to handle the larger databases with all the data security and data abstraction as well as data hiding. Code becomes very easy to handle as well as to debug. The length of a program reduces. Reusability code is one more required feature for software development which helps to reduce the length of the program. The programmer may change the platform easily. Very few changes are required to change the platform. Java is platform independent language which is used for development of web based applications, mobile apps, games, etc. Function overloading, overriding, operator overloading gives another good flavour to programming. All other basic features which are available in C can also be used in the same manner in these languages.

In this course, major features of Object Oriented Programming Language are discussed with implementation codes for few features. C++ language is majorly considered for implementation and description. Data security and data abstraction are useful features along with the major feature as an inheritance. After the completion of this short course, students will be confident to build the preliminary programs on their own.
