Answer Posted / naveen verma
Abstract Class:- its should have declared as abstract and must contain atleast one abstract method. an abstract class can be extended from either an abstract class or the class which is extending the abstract class should implement all methods of abstract method.
Interface:- In interface the methods are only declared not define the class which implementing the interface can define the method body as per its need. its not mendatory to define every method of the interface.
In really time application we extend abstract class only we when we need to modify the class. where as interface can be used to implements its method.
