Fifty

• this is a dice rolling game.
• the scoring works like this:
  • all doubles except 3s and 6s score 5 points
  • 6s score a whopping 25 points
  • 3s wipe out your score
• the first player to 50 points wins.

Below is the code for fifty NOT in applets. Convert it to an applet.

• Set up the user interface.
• Set up the roll button.
• Code the rest of the actionPerformed. Use dialog boxes (optionpanes) to deliver messages to the user. You won't need loops - only ifs.
