The 15-Tile Puzzle is a game where a player moves tiles on a 4 x 4 board to try to arrange them into a predetermined order. You are to do a simulation of this game in lab 7-8.

In lab 7, you have implemented the main game that supports the following commands:

'R': Moves a tile to the right
'L': Moves a tile to the left
'U': Moves a tile up
'D': Moves a tile down
'Q': Quit the program

'S': Save the current board
'O': Load the saved board

The save function will save the current board information into a text file. The file can be of any name in any location of your choice. You also need to decide the saved format (e.g., one number per line).

The load function will load the saved board information, which allows a user to continue to play the game from the saved one.

You also need to handle FileNotFoundException when saving and loading the game.

Grading

• 3 points: Appropriate header, commented code, runnable jar file
• 8 points: Correct implementation of the save function
• 8 points: Correct implementation of the load function
• 6 points: Correct exception handling for both reading and writing files

How to turn in the assignment

• Make sure you put the standard program header at the top of your code and modify the header appropriately.
• Follow the instructions for creating a JAR file. The Main-Class attribute of your MANIFEST file should be Lab7, because this lab is built upon Lab 7.
• Submit yourlastname_lab8.jar via Sakai by 11:59pm on Monday, June 15th.
• Your jar file should contain Lab7.java, Lab7.class, TilePuzzle.java, and TilePuzzle.class.

Let me know if you encounter any problems in this lab.
