Interface

Question

Hi all here I have a doubt as follows If we use any predefined interface then we have to make the method definition of our own but we must use the method signature(defined in the interface itself) ie; Interface does not have any definition of that method. am i having correct understanding? please anybody help me thanks in advance.

That's right - a class which implements the interface must have a method with exactly the same signature and it must be public as well. The interface itself doesn't contain any implementation for the method but the class must do.
