Listener for JTextField

A JTextField is a Swing component, so there must be a listener object for it to be useful to the program. After entering text, the user hits the enter key. This generates an ActionEvent just like clicking on a button.

The listener needs to get the text and to do something with it. Use the String getText() method to get the text in the field.

To put text into a TextField use the setText(String stuff) method.
