Thanks for that, but I'm still a little stuck:

The setColor method sets the Didge color to a color in the array:

private final Color[] colors =
    {Color.blue, Color.black, Color.cyan, Color.green,
    Color.gray, Color.magenta, Color.orange, Color.pink,
    Color.red, Color.white, Color.yellow};

Taking that into account how can I make the public method invoke the other
three to reset the location, radius and color methods.

Sorry if this sounds dumb - I am somewhat!

TIA
