    Getting the Screen Size</h3>


<pre>
    // Get the size of the default screen
    Dimension dim = Toolkit.getDefaultToolkit().getScreenSize();
</pre>
If more than one screen is available, this example gets the size of each
screen:

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