Answer Posted / priyabrata patro
listen in fact, java supports three types of structure. And they are fully implemented structure , fully unimplemented structure and partially implemented and unimplemented structure .
Now what is abstract class?
abstract class is one type of structure where exactly you can find both implemented and unimplemented method.I mean to say here it is partially implemented and unimplemented structure.So , usage of this class is to allow subclass to fullfill his own requirement by overriding abstract method defined in abstract class.And if you want to know complete information about abstract class you can contact to me in this email id priyabrata.try@gmail.com.
Now what is interface ?
interface is fully unimplemented structure where only unimplemented methods can be found out.And purpose to use this interface is to achieve run time polymorphism .
Now you will tell me that(run time polymorphism) also can be achieved by abstract class . Obviously , you can but you can not create object of interface but you can create object of abstract class by subclass (if it is a class).
