Answer Posted / tharun raj s
an abstract class contains 1)instance variables 2)concrete
methods(implemented methods). 3)abstract
methods(unimplemented methods)
An interface contains 1)abstract methods and variables which
are public static and final by default
Abstract class is written when there are certain common
features shared by all the objects
Interface is written when all the features are implemented
differently in different objects
when an abstract class is written it is the duty of the
programmer to provide subclasses to it.
An interface is written when the programmer wants to leave
the implementation to the third party vendors
