远程接口的UML类图

Question

There are 2 interfaces A and B which implement remote methods. How can I implement another interface which aggregates interfaces A and B? Or is there any other way to do it? Eg:

public interface A extends java.rmi.Remote
{
    //function declns
}

public interface B extends java.rmi.Remote
{
    //function declns
}

public interface C extends java.rmi.Remote implements A,B
{
}

gives me error saying there's a syntax error on implements

Pls help

Answer 1

public interface A {
  public methodA();
}

public interface B {
  public methodB();
}

public interface C implements A,B {
  public methodA();
  public methodB();
}


+----+     +-----+
| A  |     |  B  |
+----+     +-----+
  ^           ^
  |           |
+----------------+
|       C        |
+----------------+

Answer 2

public interface A extends java.rmi.Remote
{
    //function declns
}

public interface B extends java.rmi.Remote
{
    //function declns
}

public interface C extends A,B
{
}

Note that interface C does not need to directly extend java.rmi.Remote since it extends A and B , both of which themselves directly extend Remote .
