Scope of having an interface within a class

[prads Menon]

Hyi,

Can someone explain the scope(explain) of the program coded below.

public class A
{
interface B{}
}

--> nd also tell me what the sublass should do when it extends the above class.

Thanks and regards

Welcome to the Ranch.

It is easy to tell you what the program would do, but I think you would do better to try it and see for yourself.
