Can an interface implement another interface?

Is the following a suitable implementation of the Comparable interface?

public class Double2 implements Comparable

{

private double value;

public Double2(double theValue)

{

value = theValue;

}

public int compareTo(Object other)

{

return -1;

}

public double doubleValue()

{

return value;

}

}

You can think of the underlying “comes before” relationship as saying that for

any objects d1 and d2, d1 comes before d2.
