Answer Posted / pawan v. tak
abstract class cantains implemented as well as non
implemented methods.The non implemented methods are called
as abstract methods.if we do not provide the
implementations of all the methods of the abstract class
the class that extends this class should be declared as
abstract.
And interface contains only abstract methods, i.e no method
implementaion is there in interface.In interface all data
members are public final and static means they wont be
changed and can be called by using classname and "."
operator. If you need to change your design, make it an
interface.
