Creating a JScrollPane Container
The Swing components do not typically have scroll bars.
In order to automatically display scroll bars, you need to
insert the component in a scroll pane.
JTextArea textArea = new JTextArea(10, 10);
JScrollPane scrollableTextArea = new JScrollPane(textArea);
JList list = new JList();
JScrollPane scrollableList = new JScrollPane(list);
