Answer / vara prasad
In both Interface and Abstract classes we cannot create a
object but abstract classes can be inherited and we can
create a object for that derived class.
Abstract classes may contain concrete methods as well as an
Implementation of methods where as Interface doesn't
contain any implementation it just contains concrete
methods and to use those methods in interface we need to
inherit that interface and have to make sure that all
methods in the interface are implemented or else even the
derived class becomes an Interface.

Answer / manikandan
The interface is the one in which all the methods are empty
one but in the abstract class it is not necessary that all
the method has to be abstract .it can be only one method
that is abstract
