Answer / jenypatel86
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.

Answer / m.shanmuga sundaram rjnsoftwar
There are some subtle differences between an abstract class
and an interface
1)
A class can inherit multiple interfaces
A class can inherit only one abstract class
2)
An interface does not contain any access specifier,fields
and code. By default the access specifier is public.
An abstract class can contain any access specifier,fields
and code.
