The class Rectangle extends from Rectangle2D which extends RectangularShape. All three classes have methods for manipulating rectangles and these are listed in the Method Summary and Methods inherited from ... sections of the Rectangle api.

    protected void paintComponent(Graphics g)
    {
        super.paintComponent(g);
        ((Graphics2D)g).draw(r);
    }
 
    class Listener extends MouseInputAdapter
    {
        Point start;
 
        public void mousePressed(MouseEvent e)
        {
            start = e.getPoint();
        }
 
        public void mouseDragged(MouseEvent e)
        {
            r.setFrameFromDiagonal(start, e.getPoint());
            repaint();
        }
    }
