Object Oriented Programming Concepts

There are 6 object oriented programming concepts in Java
which are given below.
  1. Class
  2. Object
  3. Encapsulation
  4. Polymorphism
  5. Inheritance
  6. Abstraction


Class is a collection of similar type of objects which have
some common properties.


Object is any real world entity which have physical
existence either living or non-living.


The wrapping up of data and functions into a single unit (class)
is known as encapsulation.


Polymorphism is used to assume the ability of several
different forms. Or we can say performing one task in different ways.


Creating a new class form an existing class is known as
inheritance. It provides code reusability.


Hiding the complexity and showing the functionality is known
as abstraction. Showing the essential data and hiding the non essential data.

In next tutorials we will discuss these concepts in detail.
