This has nothing to do with JNI ( interfacing with C++ )

Maybe you should post to "New to Java"

If both interfaces, A & B, use the exact same method declaration, then C can implement both interfaces.

public interface A

{

public int calculate ( int a );

}

public interface B

{

public int calculate ( int a );

}

public class C implements A, B

{

public int calculate ( int a )

{

return ( a * 2 );

}
