I keep hearing on te radio that every person has to eat five fruit servings a day. But this is about phisical health. How about mental healthy diet for Java developers? I recommend to consume at least five Java books a year. JDJ has published a review of Java books that I like, which includes four books.
The fifth one is “Java Reflection in Action ” from Manning. This 250-page book has lots and lots of useful and well covered information not only about reflection, but also about proxies, class loaders, stack introspection and design patterns. A really good book.
