    // Retrieve the graphics context; this object is used to paint shapes
    Graphics2D g2d = (Graphics2D) g;

    // Determine if antialiasing is enabled
    RenderingHints rhints = g2d.getRenderingHints();
    boolean antialiasOn = rhints
        .containsValue(RenderingHints.VALUE_ANTIALIAS_ON);

    // Enable antialiasing for shapes
    g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
        RenderingHints.VALUE_ANTIALIAS_ON);

    // Disable antialiasing for shapes
    g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
