I think I actually saw it first in "Java in a Nutshell" - OK as a quick reference but not a great learning book. "Effective Java" is IMO a goldmine. Also "Java Generics & Collections" and "Java Concurrency in Practice". HTH, Ian.

Free!) <http://java.sun.com/docs/books/effective/toc.html> <http://java.sun.com/docs/books/effective/generics.pdf> is the best explanation of Java generics I've encountered, save perhaps for Brian Goetz's articles on DeveloperWorks, also free.
