This makes me think you misunderstand what I am doing.
If you care about whether an array is empty, you check whether
its length is 0 or you call empty (which checks whether the
length is 0). If you care about whether the array is null, you
use "is null". I don't understand what else you could possibly be
doing. "!= null" is just going to end up being equivalent to
checking whether the length is 0, because the elements won't be
compared if the length is 0, but it gives the false impression
that you're checking whether the array is null - hence why
checking != null is a bad idea. What am I missing here?
