class can inherit more than one interface.

methods whereas the interface can have only the abstract

Answer / abhishek

Basically both Interfaces and Abstract class sit on top. An
abstract class can have defintion and body. It's also used
when we need to implement polymorphism (Contain at least one
virtual method). However an interface contains only
declaration.

An Abstract inherit a class, an abstract class and implement
an interface. But interface can only implement another
interface.
