Abstract and interface

[Arathi Rajashekar]

Hi all,
Can an interface be declared abstract. I tried to compile the following code
public abstract interface a{
public void b();
}
It compiled fine. with out errors. If we can declare an interface as abstract interface, what is the use of it?

Becuase they are abstract?? Still not quite when to use interface though.
good luck.
