How do I correctly call the superclass(Point2D) in Point3D? As of right not I get a compilation error saying that the "x" and "y" are private access to Point2D. I believe I need something like this... String superString = super.toString( ); ----- but where would this go and how would I correctly use it to pull the x and y values for my Point3D class. Thanks for the help!
