Events can be used for many purposes besides causing a method to run when a key is pressed in Alice, such as controlling burglar alarms, checking remote sensors, or checking for system events, like printers running out of paper.

• Use one of these examples or come up with your own and describe how an event works in Alice 2.3?
  • How would an event trigger function in your example?
  • How would the event function once the event trigger was initiated using an event handler?
• Can you list, not describe, at least two other events similar to those above? In other words, can you come up with a unique example?
