For anyone out there who has an interest in using in Java 5.0 and needs a good, concise, quick, reasonably priced and accurate guide to the new features, I found the following extremely useful:
http://www.amazon.com/exec/obidos/ASIN/0072258543/ref%3Dnosim/deliciousmons-20/002-9381773-9618440
The best thing is that it’s less than 200 pages long and gives good, clear illustrations by short example.
Note this is the American Amazon site. The book should be available locally in all cases.
Cheers,
N
