Although I know this should be the simplest thing in the world, I'm having trouble converting a 2-dimensional String array to a 2-dimensional int primitive array.
int[][] intResult=Integer.parseInt(strResult[1][0]);
where should the brackets go on the right side of the expression...
i guess i'm just missing something here.

HI Bill,

parseInt() can deal with only ONE string and spits out ONLY ONE int. So you would have to run a for loop to convert all objects in String[][] to int[][]...it can't be done by single API call.

Thanks

is there any other way to do this w/out the for loop?
implicit conversion?

I'm afraid not: you're stuck with doing a nested "for" loop.

Why are you so concerned with this? A nested "for" loop only adds a few extra lines to your code.
