Java Applet - ArrayIndexOutOfBoundsException (pt 2)

I fixed my previous problem. But now when on my tile map... if I try to go 9 tiles to the RIGHT, and on trying to get to the 9th tile.... I will get this error:

I have tried many solutions, all of which have failed.

I believe the problem is you mix up the coordinates. You use X as the left-right coordinate and Y as the up-down, when it should be the other way around (or you should mirror your board).

Upon going right, you increment X, and on your board, that means effectively you move one row down. Since the board has 8 rows, the 9th move takes you out of bounds.
