A class extending a class and implementing an interface with same methods ?

[K Srinivasan]

if a class extends another class and implements an interface both with the same method , which function will it implement ??

eg:

interface a
{
 public void show();
}

abstract class b
{
 abstract public void show();
}

public class c extends b implements a
{
public void show()
 {
  System.out.println("hi");
 }

public static void main(String[] args)
 {
   c t = new c();
   t.show();
 }
}

which show() does c implement ??

thanks.

The important thing is that the rules for the implementation of interfaces and abstract classes have been obeyed.

So, if you do

a myA = new c();

myA.show();

or

b myB = new c();

myb.show();

both will do the same thing...

From a pragmatic standpoint, what's the difference? If the signatures are the same, the implementing subclass will be an instance of both the superclass and interface (unless I'm misunderstanding something).
