Object-Oriented Programming

Object-Oriented Programming or OOPs, refers to languages that use objects in programming.  OOPs is a programming paradigm that is based on the concept of “objects”, which contain data, in the form of fields (also known as attributes or properties), and code, in the form of procedures (also known as methods). 

The aim of OOP is to bind together data and the functions that operate them, so that no other part of code can access this data except that function.

OOP concepts include:

  • Polymorphism – Polymorphism refers to the ability of OOPs programming languages to differentiate between entities with the same name efficiently.
  • Inheritance – Is the mechanism in java by which one class is allowed to inherit the features of another class.
  • Encapsulation – Is the mechanism that binds together code and the data it manipulates.
  • Abstraction – Is the property by virtue of which only the essential details are displayed to the user.
  • Class – Is a user defined blueprint or prototype from which objects are created.
  • Object – Represents the real life entities.
  • Method – Is a collection of statements that perform some specific task.
