No offense guys, but the for and while loop approach is identical. I use the for loop, but it gets compiled into the same jvm code.
Looking at the original do/while code, it looks ok. I'd be surprised if the for approach works, but it's probably worth a shot since it will only take a couple of minutes to try...
