Wrestling with Java has been useful for me trying to understand what the basic ideas are. As I teach Cad, general computer stuff, Perl, am Webmaster, computer fixing slave etc. I'd have to wait a long time to fully master the subject. One of the things I have found out about teaching, your students may or may not learn what you are teaching, but you most certainly will.

Or, at the very least it will make my ignorance public. I've done that a time or two already</p
