Splitting String from Arraylist (java)

Question

FIXED! Thanks everyone!

Okay, so I am not sure why this is giving me an ArrayIndexOutOfBoundsException..

al is an arraylist holding values such as:

2,6,m
1,7,w   
5,3,c   
0,4,w
1,6,w
2,3,w
1,5,w

Here is where I am trying to get each arraylist index, split it into: row, col, letter. It is saying that temp[2] is outofbounds. Why? I mean the split method should make 3 parts, 0,1, and 2. So why is 2 giving me fits. I ran some tests and it also gave outofbounds for temp[0] and temp[1] calls.

    for (int i = 0; i < al.size(); i++) {
        String[] temp = al.get(i).toString().split(",");
        System.out.println(temp.length);
        System.out.println(temp[1]);
        if (temp[2].equals("m")) {
            boardTiles[Integer.parseInt(temp[0])][Integer.parseInt(temp[1])].setIcon(mousetile);
            boardTiles[Integer.parseInt(temp[0])][Integer.parseInt(temp[1])].putClientProperty("mouse", true);
        }
        if (temp[2].equals("c")) {
            boardTiles[Integer.parseInt(temp[0])][Integer.parseInt(temp[1])].setIcon(cheesetile);
            boardTiles[Integer.parseInt(temp[0])][Integer.parseInt(temp[1])].putClientProperty("cheese", true);
        }
        if (temp[2].equals("w")) {
            boardTiles[Integer.parseInt(temp[0])][Integer.parseInt(temp[1])].setIcon(metalwall);
            boardTiles[Integer.parseInt(temp[0])][Integer.parseInt(temp[1])].putClientProperty("wall", true);
        }
    }

Am I utilizing the String[] with the split method wrong or something? Thanks, -Austin

EDITS:

I just ran a for loop on the arraylist, all of the values are there.

boardTiles[x][x] is a 2d array of JButtons.

Exception is occuring at index: 1.

the .length is showing is 1 as well.

Are you sure you inputs are always like the example inputs you gave above? Try printing out the input each time to see which input is giving you the error. — Danny

What does temp.length show before you get the exception? It looks like one of your strings doesn't have the right format. — trutheality

boardTiles probably doesn't have the size of some values defined in your input array.

@jeurgend can't be, before I do this part it runs a boardbuilder method which displays fine in the JFrame. So that's not the issue.

Do a print of al.get(i) and double check that it is indeed a comma separated string of values.
