Yeah at the top of the exception it cites that line then it cites a stream larger than my command prompt buffers capabilities here:


nO = t.getOptimalNodes(n,utilities.invert(a));

Aussie using the length variable produces the same error.

What are you suggesting that the Array class is inaccurate or flawed?

Yes aussie your right I guess I never really reviewed the array API very much. In any case I appreciate your help. I will delve into this with your suggestions.

There is a level of incursion, but I believe that as soon as I reassign n it is no longer referencing the argument. Norm, do you mean a local variable that wasn't initialized?

May I ask first, is there any other way I could get a null pointer there? Or, do you need more of the code to know for sure? In my head I keep getting this nagging urge to just stop myself and...

What do you mean by explicitly an array?

It shouldn't be:


n=utilities.increment(n);
for(Tile cur:t.nodes){
if(cur!=null){
n[Array.getLength(n)-1] = cur;

I get a null pointer at:


n[Array.getLength(n)-1] = cur;

not an arrayIndexOutOfBounds, but a null pointer? I didn't think you get get a null pointer on assignment, because after all aren't...
