Hi,

I am currently working on a project where there is a two-dimensional 50-by-50 grid of data objects that represent a single square in the grid. This is a "playing surface" where other objects (Soldiers, recon, etc) while be moving about in sometimes random ways. Each of the soldier elements has a search loop that takes in adjacent squares in all directions and "looks" for enemies. My problem is when a soldier object gets to the edge of the grid and tries to "look" in squares that don't exist because they are beyond the "playing surface", I get an ArrayIndexOutOfBoundsException, which I understand why, but I am not sure how to fix it. I tried putting in a try catch block, but that doesn't help repeated moves. Any ideas on how I can help fix the boundaries?

Thanks,

DRW

You need to check to make sure that (x >= 0 && x < arr.length) && (y >= 0 && y < arr[x].length). Any indices outside of these bounds are illegal.
