Abstraction in Java?

Question

Today i heard from my friend, that encapsulation is not only achieving information hiding but also abstraction. How does it achieve?

public class employee {

           


        

Answer 1

It seems encapsulation and abstraction has got everyone confused. If you ask me, those are poles-apart topics and there is absolutely no scope of confusion in this.

abstraction happens when you use "abstract" keyword, and encapsulation happens when you create a class. a good implementation of encapsulation involves making all your data members private.
