Answer / prapanch
if the developer wants some methods which are implemented
in the super class and some methods which will be
implementd by him then he will go for abstract class.
because in abstact class all methods need not to be abstact
in nature. but in interface all the methods must be
abstract and so the developer will not get any implemented
code from the interface. you will use interfaces when two
different teams are working for a same requirement then an
interface will act like a medium with which they can
interact and all the teams will be in line.so your team and
other team will implement the same method names but with
difffeerent implementation code.

Answer / vinaykumar
If you want to provide your own services for methods we
use interfaces.If you want to provide your own services or
to use the services of the methods in your class then wego
for abstract classes.abstract class is partially implemented
and partially unimplemented class where as interface is
completely unimplemented.both of the objects can not be
created.
