Is there any way to include the name of the interface when implementing the method

问题

Is there any way to include the name of the interface when implementing the method? If I have to implement 3 interfaces, then it would be hard to remind me where the implemented method comes from.

If I have 2 interface required to implement the same method name. How can I tell which method I am implementing?

public interface BarInt {
void method();
}
public interface GeeInt{
void method();
}
public class Foo implements BarInt, GeeInt{

@Override
public void method() {
    // TODO Auto-generated method stub

}
}

Thanks

Yes, you can just use a @see javadoc comment

public interface BarInt {
    void method();
}

public class Foo implements BarInt{

    /**
     * @see BarInt#method()
     */    
    @Override 
    public void method() {
        // TODO Auto-generated method stub
    }
}

Novaterata's answer in good, this is a similar approach with annotations.

You can always roll your own annotations.

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.SOURCE)
public @interface Source {

    Class value();

}

Then you can use it like this:

@Source(List.class)
@Override
public boolean add(Object o) {
    return false;
}

With the retention policy of Source the annotation will not be part of the bytecode. It only serves as additional information for the reader, IDE and compiler.

Design wise name of method would reflect what the method does and you should be able to co-relate with the Interface the method belongs to.

De-bugging wise, most editor will take you the implemented Interface and method on few key strokes/clicks.
