define oops concept with example
Answer / lata bheemanagar bp
Hi Friends, Good Evening!!
We write Object Oriented Programs.
now, What is Object? --->It is a Real World Entity.
Say for Example:BOX
I want to write a program on this real world entity.It does not mean that i will insert this BOX inside the CPU and write some LOGIC.
I take the properties of this BOX like Height,Width,& Diagonal etc...embed them in a class.and create 'N' number of Objects of this class with different sizes.
This is how we can relate the real world entities in OOPs.
There are mainly 4-types
1) Abstraction---> Hiding complex implementations from users & providing required functionalities to users.
Exp: Birds
We invented 'FLIGTHS' based on the mechanism of Birds,so flight is derived from the base of 'BIRDS'.
2)Inheritence.--->Aquiring properties from one class to another class.
Exp: Human Heridity
aquiring properties from one person to another.
3)Encapsulation->Technique of making fields Private & Providing a Public method to access Private field.
Exp: Pen
In Pen INK is the important thing but it is hiding by some material.
4)Polymorphism->(Many Forms):One Object can take different forms in different situations.
Exp: Crocodile
Crocodile live in differently in Land & in Water.
