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.

difference between abstraction and encapsulation with progarammatic eg. hi,just recently i went for an interview .The interviewer asked what is the difference between abstraction and encapsulation with programmatic eg. I gave the answer as encapsulation mean hiding the relevant data which is not useful for the user, eg a electric fan .hiding the information how the electricity is converted into machanical energy. abtraction showing only the relevant data to the user eg electric fan. it look ,its color ,it design etc only relevant data. Then the interviewer asked me, give me some programmic eg .I Said Let assume a web form having control like textbox,button etc. The user can view textbox,button etc this is the eg of abstraction and when the user click on the button how he is redirected is not known by the user is the eg of the encapsulation. Am I Correct .was the answer given by me is perfect .now i am planing to go for an another interview should i give the same answer.IF not please suggest me a better answer.with some good eg Please help
