Answer / praveen
If a user want to interact with my application he need an
interface. With the interface the user can access the
specific methods of a class that implemented the interface.
For example user want to call a method. He already know the
specific class implemented that interface, then he can call
the method through reference object.
Abstract class is used whenever a user restricted to
inheritance but not taking instance of a class or if any
methods are there that should be implement by the user.
