Requirements of ***Java eclipse*** program

- The program should give the user a 4 choice menu (Menu 1: Read a maze file 2. Show current maze map 3. Start game 4. Exit )
- The menu should work allowing the user to choose to read a maze file (posted below) , show the current maze map, start the game, and exit
- The user should be able to input commands to figure out the maze path (examples: u 3 - moves upward 3 rows, r 2 - moves to the right 2 columns)
- The map should consist of 8 rows and 8 columns
- The map of the maze (# : wall, ‘ ‘ : the road, S: a starting point, E: an ending point)
- If one game ends the program repeats until a user chooses ‘Exit’
