Generic array creation error

private ArrayList<Integer>[][] potentialList = new ArrayList<Integer>[9][9];

Someone, please explain to me why this statement gives me a:

--------------------Configuration: <Default>-------------------- 
SolveSudoku.java:31: error: generic array creation 
private ArrayList<Integer>[][] potentialList = new ArrayList<Integer>[9][9]; 
//The error is on the "n" of new ArrayList.
Process completed.

• Andrew Thompson: Why not simply private Integer[][] potentialList = new Integer[9][9];? Or to put that another way, why not simply use an array?

Answer 1

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.
