Creating a JScrollPane Container
The Swing components do not typically have scroll bars. In order to
automatically display scroll bars, you need to wrap the component in a
scroll pane.
// Create a scrollable text area
JTextArea textArea = new JTextArea();
JScrollPane scrollableTextArea = new JScrollPane(textArea);
// Create a scrollable list
JList list = new JList();
JScrollPane scrollableList = new JScrollPane(list);
