Ah, I just realized that this isn't a Java 7 thing - you are just suggesting that I use the iterator rather than the index. I know it is a minor detail, but I generally tend to use an index for array iteration to avoid the heap allocation. Is there any advantage to using the iterator, aside from brevity?
