  • Why not simply `private Integer[][] potentialList = new Integer[9][9];`? Or to put that another way, why not simply use an array? – Andrew Thompson May 21 '12 at 01:56

We don't know what you want to do, maybe:

private ArrayList<Integer[][]> potentialList = new ArrayList<Integer[][]> ();

This would be a list of 2dim-Integer-Arrays.
