    Creating a JFrame</h3>

A frame is a component container that displays its contents in a
top-level window with a title bar and buttons to resize, iconify,
maximize, and close the frame.

<P> Unlike most Swing containers, adding a component to a frame is
not done with the <code>JFrame.add()</code> method.  The reason is that the
frame holds several panes and so it is necessary to specify a
particular pane to which to add the component.  The pane that hold
child components is called the content pane.  Here is an example that
adds a text area to the content pane of a frame:


<pre>
    // Create the frame
    String title = <font color="#0066ff"><i>"Frame Title"</i></font>;
    JFrame frame = new JFrame(title);
    
    // Create a component to add to the frame
    JComponent comp = <font color="#0066ff"><i>new JTextArea()</i></font>;
    
    // Add the component to the frame's content pane;
    // by default, the content pane has a border layout
    frame.getContentPane().add(comp, BorderLayout.<font color="#0066ff"><i>CENTER</i></font>);
    
    // Show the frame
    int width = <font color="#0066ff"><i>300</i></font>;
    int height = <font color="#0066ff"><i>300</i></font>;
    frame.setSize(width, height);
    frame.setVisible(true);
</pre>
