What is Object Oriented Programming?

 OOP is a programming paradigm that represents concepts as "objects" that have data fields (attributes that describe the object) and associated procedures known as methods.

Object Oriented Programming is a programming that relies on the concept of classes and objects.

Advantages of OOP

•  Provides a clear modular structure for programs
• OOP makes it easy to maintain and modify existing code (new objects can be created with small differences to existing ones)
• OOP provides a good framework for code libraries
• Software components can be easily adapted and modified by the programmer 

Many of the most widely used programming languages (such as C++, Java, Python, etc.) are multi-paradigm and they support object-oriented programming to a greater or lesser degree, typically in combination with imperative, procedural programming

In this article we will talk about OOP with Java language.

Concepts of OOP

What is an Object?

• A Java class is a group of Java methods and variables

• Object is an instance of a class

• Example class Person

   { // Methods

 

   // Variables } 

Encapsulation:-  

Notion of encapsulation (or OOP Encapsulation) refers to the bundling of data, along with the methods that operate on that data, into a single unit

Abstraction:-

Abstraction is the concept of object-oriented programming that "shows" only essential attributes and "hides" unnecessary information

Inheritance:-

Inheritance is the procedure in which one class inherits the attributes and methods of another class

Polymorphism:-

 describes situations in which something occurs in several different forms
