JTextArea textArea = new JTextArea();
JScrollPane scrollPane = new JScrollPane(textArea);
content.add(scrollPane);

Figure 15-17 shows how a JTextArea looks within a JScrollPane and outside a JScrollPane . In
the JTextArea not in the JScrollPane , you can't see the text that falls below the bottom screen
border. By design, moving the cursor into that area doesn't cause the content at the top to
move up.
