It is basically used for achieving
1.Encapsulation(or information hiding)
2.Inheritance
3.Polymorphism
Encapsulation
--The encapsulation is the inclusion within a program object of all the resources need for the object to function - basically, the methods and the data. In OOP the encapsulation is mainly achieved by creating classes, the classes expose public methods and properties. The class is kind of a container or capsule or a cell, which encapsulate the set of methods, attribute and properties to provide its indented functionalities to other classes.
Inheritance
--Ability of a new class to be created, from an existing class by extending it, is called inheritance.
Polymorphism
--Polymorphisms is a generic term that means 'many forms'. More precisely Polymorphisms means the ability of a same function exibhiting different forms based on context.The function only differes in the arguments and has the same name in all the classes where it is used.
