Java heap space?

[javanewbie]

int aiNumbers[][] = new int[number] [number];

what is the maximum number that can be entered here?

Allocation, as you have done it, is a recurrent discussion issue that is better approached by writing a short test stub to do nothing except the allocation and just see what happens.

I wrote a program recently to test such a thing, ran through five or ten loops before the memory issue slowed things down. Start with 1024 x 64 or something, I would not think a [1024][1024] to be too far from blowout, but we have to realize that the two numerics multiply as a [][]

public class HeapHog
{
    public static void main(String[] args)
    {
        try
        {
            int[][] Flint = new int[1024][1024];//
            Flint = null;
            System.out.println("Suprisingly large");
        }
        catch(Exception e)
        {
            System.out.println(e.getMessage());
        }
    }
}

output:

Suprisingly large

If you find a use for a 1024 by 1024 memory space, you will be in the database forum or something. Possibly some games could use this sort of space.
