Am I wrong in not studying these operators? I remember earlier this year I read "An SCJP Primer" or something, an old SCJP preparation book, and read something about the bitwise operators, but I didn't really pay attention to it, because, as far as I can tell, it's not in Sun's Exam objectives. K&B's Study Guide also didn't mention them, so I was comfortable in my assertion that I didn't need to know about them.
However, I've been doing mock exams lately and they seem to come up time and time again in just about every mock exam. Even in the little cow-herding thing on this site. Should I study this material, may it make its way on the exam, or is this just a sign that the mock exams are a bit outdated and I shouldn't pay attention to them?
