Answer Posted / manish sharma
Abstract classes Interfaces
Abstract classes are used only when there is a “is-a” type
of relationship between the classes. Interfaces can be
implemented by classes that are not related to one another.
You cannot extend more than one abstract class. You can
implement more than one interface.
Abstract class can implemented some methods also.
Interfaces can not implement methods.
With abstract classes, you are grabbing away each class’s
individuality. With Interfaces, you are merely extending
each class’s functionality.
