Since the second edition is covered with many great features of J2SE 5.0, I believe that there are many new topics which are valuable to us.
The sample chapter got a taste for Tiger's new feature(Generics, foreach and Enumerations)...
I love that chapter also... I do believe that there are many of such Tiger's new features recipes in other chapters as well...
