• Escape Room Code Decoder - This project is aligned with AP CSA Unit 1, Topic 1.15. In this lab, you will use a provided class called CodeGenerator to create a random master code that can be used to help escape the escape room maze. At the end of each room, a room code will be found. This program will interpret the room code, providing clues for the next room as well as directions to the next room, or it will allow you to exit the maze and win.
