Should be required reading for every developer who writes Java.

A long overdue read of this (updated) Java classic. I was lucky enough to see the author's presentation at the recent Devoxx conference.

Invaluable.

meh

needs more real life application

i like the writing style though

some chapters definitely worth skipping

Excellent tidbits of java wisdom. And it really is a stylistic thing; most of the time I go to check something it isn't covered. But reading all of this will definitely improve your Java

Read this book as a part of my internship.
This book is not for beginners and expects you to know the basics already.
This book is your guide to customary and effective usage of the java language. It contains both warning and tips. Ideas to work around common problems. Common pitfalls to avoid. It also gives you an idea about how the underlying mechanism works. While the central focus is java, most principles apply universally.
