That's a bit unfair.  Most code in books has a lot of that kind of thing stripped out to focus on illustrating the subject at hand without adding too much noise.  It's pretty common for error checking, return codes, exceptions etc to fall by the wayside to aid clarity. Yes, forgive me for being a bit bitter. I have to work with these obnoxiously slightly broken classes. ;) But any books that show off this terrain class... *Shudder*
