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.
