Object Oriented Programming Paradigm

Overview

Object Oriented Programming( in short we call OOP) is a programming paradigm to design software applications using classes and objects. We focus on real-world objects while programming the solution. There are several benefits of object-oriented programming. Object-oriented programs are modular, reusable, maintainable, and extendable.

Let’s understand the two main concepts of object-oriented programming:

  • Class
  • Object

Class

A class is a prototype or blueprint to create real-world objects. The class definition models the object. It defines the object state and behavior of the object.

An object’s state can be defined by data fields or properties. Object behavior is the functions that act on the object data.

Object Oriented Programming

Object

Objects are instances of classes. An object is an entity that has a state(properties) and behavior(methods). An object can be a physical or a logical entity. For example, person, car, book, fruit, etc. Objects can interact with one another in the program.

Examples

Some examples of object-oriented programming languages are as follows:

  • C++
  • C#
  • Java
  • Kotlin
  • Python
  • Smalltalk
