Question

Here is a Java question
How can I implement the inner class’s interface in outer class?

I try the following, but in vain. Thank You

class A implements interface B.C{
   static class B{
        interface C{

        }
   }
}

I would do like this :
Assuming both the classes are in same package with proper imports.

public class Nestedinterface {
     public interface NestI{
         void show();
     }
}

public class NestedinterfaceImpl implements NestI {
    public static void main(String a[]) {
        NestI n = new NestedinterfaceImpl();
        n.show();
    }
    public void show() {
        // TODO Auto-generated method stub
        System.out.println("Hello world");    
    }
}
