e598. Getting the Screen Size

    // Get the size of the default screen
    Dimension dim = Toolkit.getDefaultToolkit().getScreenSize();

If more than one screen is available, this example gets the size of each screen:

    GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
    GraphicsDevice[] gs = ge.getScreenDevices();
    
    // Get size of each screen
    for (int i=0; i<gs.length; i++) {
        DisplayMode dm = gs[i].getDisplayMode();
        int screenWidth = dm.getWidth();
        int screenHeight = dm.getHeight();
    }
