private void createContents()
{
JLabel label = new JLabel("Hi! I'm Larry the label!");
}
add(label);
// end createContents
This adds the label to the window.

public static void main(String[] args)
}
// end class SimpleWindow
{
new SimpleWindow();
} // end main
This instantiates an anonymous window object.
