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.

Hi Students, This is Rakesh P, Software Developer from Chennai, India. I completed my Engineering (Computer Science) in May 2015 and then started my professional journey as a Software Developer. Being a passionate student, I have been taking seminars during my college days which in turn helped me to secure a University Rank among the Anna University Affiliated Colleges. I thought of sharing my knowledge even after starting my career.

That's when I started a YouTube Channel named Programming Line (Aug 2017). During the initial days, I have taken OOPs, Java, Software Design Patterns, etc by myself in Tamil, Telugu, and English. Students asked me to take other software courses like Android, Selenium, JavaScript, etc.

I wish to take those courses by myself but I didn't find time because I am occupied with my office work. That's when I asked my Industry friends and experts to join me in this mission. They have delivered the courses exclusively for Programming Line. At some point in time, I realized that I can't extend to pay from my pocket. Then, I made those intermediate and advanced part of courses to paid but I always make sure that courses are very affordable.

Disclaimer: Programming Line is not a registered company. It's just a brand (YouTube channel and website) and delivering the courses under that brand.
