There is no difference in the functionality of these two.The
only difference is that a class cannot extend an abstract
class if it already is extending some other class.An interface
on the other hand can be implemented in any situation which
makes them very powerful.Also user defined exceptions can be
defined within an interface itself, which is not the case with
an abstract class.
