Hi
By default all methods in an interface is abstract becuase you cannot provide any implementation for interface methods. It is duty of the concrete class implementing the interface to implement those method. You don't need to use the keyword "abstract" while declaring methods for interfaces. It is already there. But, if you want to you can use it. However, explicit use of abstract keyword in interface declaration is considered to be old-fashioned.

Thanx
