I would say you're caught in the iterator "routine" so many fall prey
to... you should not be using an iterator when working with an ArrayList
! You should be iterating the "old fashioned" way ... using direct
get(int) .. these don't entertain the concept of
ConcurrentModificationException. It's faster too.
No. I mean, this is just really terrible advice. Please don't ever give
anyone advice again. You're really not helping.
