Message:

Use of defining a class as abstract

Hi..

An abstract class is defined so as to give a generalised form which can be shared by its subclasses. Sometimes a situation may occur where in one need to define a superclass which can declare a structure for its subclasses but cannot create the meaningful implementation for a method.

So the subclass according to its necessity extend this abstract class and use the methods decalred with its own customized implementation of the method.
