Answer Posted / amit upadhyay
interface is collection of abstract method.we can not
define any method in interface.we can implement that
abstract method by using the class.there is a restriction
in interface that you have to implement all the abstract
method in the class which is declared in interface.and we
can not create an object of interface.if we want to execute
the interface method then we have to implement first that
interface in any class after that create the object of
class ,then we can access execute that method
but in class we have to define the methods, which is
declered.we can also access that method through the object
of the class.
