Unfortunately, I haven't got a clue where to start :confused:
I'm using a program called IntelliJ which I'm totally unfamiliar with, I've never used it before.
For part 2, I have to program a tile puzzle game.
Any tile next to the gap in the 9x9 grid can be moved to fill the gap by clicking the tile. Your program should allow the tiles to be randomly shuffled, and should also detect when they are correctly arranged in numerical order, and indicate this in some way (e.g. pop-up alert). You should be able to change the number of tiles in x and y simply by changing some variables.
If anyone could offer me any help in either of these tasks I would be EXTREMELY grateful.
