Friends, what is the meaning of abstract in Java?

We see abstract class, abstract method...

What is the word mean abstract?

HI

We usually write Abstract classes when we want to give some default functinality to all the other classes who are of our type(sub-classes of this abs class) and in most of the cases we write abstract methods in the Abs class to force the concrete class to override the method and provide a business logic for the same.

Let me know if this does not make sense for you.

Abstract means that the method is declared but not defined. A descendant of the parent class with an abstract method must implement that method to make it work.
