Ojected Oriented Programming

 Core OOP concepts

1)Class

2) Object

3)Inheritance

4) Polymorphism

5)Encapsulation

6)Abstraction

7)Interface

Object

       It is a real time entity, combination of states and Behaviour

      Object is a memory reference of a class

      Object is the instance of class

Eg: car, bike, dog

Class

      Class is a template/blueprint or prototype (eg.invitation)

      Class is a overview 

Polymorphism

       Poly means many ; morphism means changing faces. It has two methods

      Method overloading 

      Method overriding

      I)Method overloading - definition is different of this two  .Activity (with what) 

eg: write(pen) write(pencil) from this example the activity is same for this two but the things is different.

     II) Method overriding - different definition . Activity(by whom)

Eg: parent(cook)   child(cook) from this example the activity of the person is same but the taste is different both food has a different taste

Encapsulation

       Data protection,Data hiding, Data binding

       Store our information privately, activities also private. 

        Eg: secret-->friends, account-->only me

        Data binding: information-->personal,friends,relatives,public

Inheritance

       Generation characteristics (efficient memory management)

       Heritage

     Eg: grand parent-->parent-->child

Abstraction

         Showing only necessary data hiding unwanted data. eg: body

Interface : rules
