GUI Interfaces

• Consider converting the Mortgage program into an applet
• Instead of communicating to the user via the standard input and output files (System.in and System.out), use GUI features

• Label

  to make annotations in the window

  TextField

  to permit the user to input text

  Button

  a push-button to cause an action

  TextArea

  similar to TextField, but

  • may contain a large amount of text
  • permits viewing with scroll bars

• Program waits for the user to enter data into the fields and signal via the push button that fields have been filled in
