abstract means when don't have definition but it has only
declaration is called abstract class,and abstract class

interface means in the concept of multiple inheritance we
use interface for declaring the subclasses instead of class

Answer / shubham soni
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.
