How do I write a static method for distance between two points using Point2d?

Hi, 


---
public abstract class Point2D
extends Object
implements Cloneable
The Point2D class defines a point representing a location in (x, y)
coordinate space.

This class is only the abstract superclass for all objects that store
a 2D coordinate. The actual storage representation of the coordinates
is left to the subclass.

distance
public static double distance(double X1,
                              double Y1,
                              double X2,
                              double Y2)Returns the distance between
two points.

Returns:
the distance between the two sets of specified coordinates.

Here's the webpage this is from:
http://java.sun.com/j2se/1.4/docs/api/java/awt/geom/Point2D.html

This page has a full explanation and some sample code of how to use
the class.

The reply to my question gave me nothing - I already had access to the
same sites which did nothing to explain how to set up the method.
