The showInputDialog methods of JOptionPane allow a user to be prompted for input via a dialog when required. On the other hand, the JTextField component allows a permanent text input area to be displayed within a GUI. Find the documentation for this class. What input causes an ActionListener associated with a JTextField to be notified? Can a user be prevented from editing the text in the field? Is it possible for a listener to be notified of arbitrary changes to the text in the field? (Hint: What use does a JTextField make of a Document object?)
You can find an example of a JTextField in the calculator project in Chapter 7.
