Multiple Interfaces extending in Java

Question

I need to implement a Facade design pattern with multiple inheritance of interfaces in Java or to be correct Facade with Bridge design pattern. I know this is possible because I saw it in as a part of one system, but I don't remember the implementation very well.
Here is my implementation so far:

public interface IOne {
public void methodOneIOne();
public void methodTwoIOne();
}

And its implementation:

public class One implements IOne {
@Override
public void methodOneIOne() {
    System.out.println("methodOneIOne()");
}
@Override
public void methodTwoIOne() {
    System.out.println("methodTwoIOne()");
}  }


public interface ITwo {
public void methodOneITwo();
public void methodTwoITwo();
}
public class Two implements ITwo {
@Override
public void methodOneITwo() {
    System.out.println("methodOneITwo()");
}
@Override
public void methodTwoITwo() {
    System.out.println("methodTwoITwo()");
}}

And the facade:

public interface IFacade extends IOne, ITwo {}

So, from here I don't know where to go. If I create a class that implements IFacade, then it will be required to implement all of the methods, and this isn't what I want.

Answer 1

What are you actually trying to do with your facade class? If you are just trying to pass through most methods, possibly modifying a few then a dynamic proxy might be what you want.

Otherwise you would in fact have to implement all methods of IFacade, as Java does not allow you to use multiple inheritance, so you could not extend both One and Two.
