If you program in Java, you _must_ read this book. It is a real eye-opener to the kind of traps in your code you wouldn't even imagine could be there.

I can guarantee you have written at least one of these issues into your code. And QA never caught it. And it is out in the wild RIGHT NOW. Arrgh!!

Full review also on my blog:

Java Puzzlers is not so much a book, but a collection of obscure corner cases in the Java programming language. The author (Joshua Bloch) is well known as the author of "Effective Java" which is widely regarded as the premier text for the language, and furthermore he is one the designers and authors of the Java Collections Framework. So to say the least, he knows his stuff.

Each chapter of the book features a collection of "puzz

If you are a Java-Guru this might be fun to read. I found a lot of the puzzles more annoying than educational (especially the problems regarding unicode). In general, I found the puzzles to be overly esoteric. If you want to learn something about Java, pick one of Joshua Bloch's other (excellent!) books.

This books has a lot of good puzzles designed to make you think about how Java works.

Do not read this book if:
- you're looking to learn about the fundamentals of algorithm design and analysis.

Do read this book if:
- you'd like to know more about Java, the JVM, the intricacies of OOP, or the history of some cool visual illusions.

This book needs no introduction. A very fun and insightful read for those who want to master Java.
You wont find here good job interview questions , and you wont learn practical things about Java.
Most of the puzzles here are about cases you will probably never encounter. But it is a fun read that will show you that there are many things you don't know about Java .
Also, this book can make you more perceptive about details in code you usually don't notice.

I had no idea about all the things that I didn't know :)
Java is a complicated language and after reading this book you'll think so too. I have also read Joshua Bloch's Effective Java and it's a good companion book for this one; they're book very good and worth the a read (or two).
Most of the problems won't appear in practice if you are following best practices and keep code clean and concise. Book is fun but will be mostly useless for experienced Java programmer.
Great way to learn the corner cases of the Java language up to Java 5. Java 6 and 7 editions would make interesting reads, when available.
Owen Lindsell
For nerds only. Mildy interesting, but not the kind of thing you'd want to use for interview questions.
Not terribly useful or entertaining but the appendix is worth going through.

boring boring boring and did I mention boring?
