• A type of event-driven programming.

• A type of application that uses graphics.

An applet:
• Waits for the user to do something, e.g.,
  • move the mouse
  • click the mouse
  • press a key
• Processes that event
• Does something based on that event

For example:

• the program waits until you press a button,

• the program sees that you pressed a button,

• the program then does something based on the fact that  you pressed that button, e.g.,
  • clear the screen
  • restart a game
