    Professor Kitaoka's illusions are, quite simply, astonishing. Words cannot do them justice, so you owe it to yourself to take a look. He has two volumes available in Japanese [Kitaoka02, Kitaoka03]. An English translation encompassing both volumes is coming soon [Kitaoka05].

    You won't be disappointed. We thank Tom and Ray Magliozzi of Car Talk for providing jokes for us to steal, and we thank their legal counsel of Dewey, Cheetham, and Howe for not suing us. We thank Josh's wife, Cindy, for helping us with FrameMaker, writing the index, helping us edit the book, and designing the decorative stripe at the beginning of each chapter. Last but not least, we thank our families— Cindy, Tim, and Matt Bloch, and Ricki Lee, Sarah, and Hannah Gafter— for encouraging us to write and for putting up with us while we wrote.

    Introduction This book is filled with brainteasers about the Java programming language and its core libraries. Anyone with a working knowledge of Java can understand these puzzles, but many of them are tough enough to challenge even the most experienced programmer.

    Don't feel bad if you can't solve them. They are grouped loosely according to the features they use, but don't assume that the trick to a puzzle is related to its chapter heading; we reserve the right to mislead you. Most of the puzzles exploit counterintuitive or obscure behaviors that can lead to bugs.

    These behaviors are known as traps, pitfalls, and corner cases. Every platform has them, but Java has far fewer than other platforms of comparable power. The goal of the book is to entertain you with puzzles while teaching you to avoid the underlying traps and pitfalls.

    By working through the puzzles, you will become less likely to fall prey to these dangers in your code and more likely to spot them in code that you are reviewing or revising. This book is meant to be read with a computer at your side.

    It should support release 5.

    You can download the source code for the puzzles from. Unless you're a glutton for punishment, we recommend that you do this before solving the puzzles.

    It's a heck of a lot easier than typing them in yourself. Most of the puzzles take the form of a short program that appears to do one thing but actually does something else.

    It's your job to figure out what the program does.

    To get the most out of these puzzles, we recommend that you take this approach: 1. Study the program and try to predict its behavior without using a computer. If you don't see a trick, keep looking. Once you think you know what the program does, run it. Did it do what you thought it would? If not, can you come up with an explanation for the behavior you observed?

    Think about how you might fix the program, assuming it is broken. Then and only then, read the solution. Some of the puzzles require you to write a small amount of code. To get the most out of these puzzles, we recommend that you try— at least briefly— to solve them without using a computer, and then test your solution on a computer. If your code doesn't work, play around with it and see whether you can make it work before reading the solution.

    Unlike most puzzle books, this one alternates between puzzles and their solutions. This allows you to read the book without flipping back and forth between puzzles and solutions. The book is laid out so that you must turn the page to get from a puzzle to its solution, so you needn't fear reading a solution accidentally while you're still trying to solve a puzzle.

    We encourage you to read each solution, even if you succeed in solving the puzzle. The solutions contain analysis that goes well beyond a simple explanation of the program's behavior. They discuss the relevant traps and pitfalls, and provide lessons on how to avoid falling prey to these hazards.

    Like most best-practice guidelines, these lessons are not hard-and-fast rules, but you should violate them only rarely and with good reason.

    These references aren't essential to understanding the puzzles, but they are useful if you want to delve deeper into the language rules underlying the puzzles.

    These references are useful if you want to delve deeper into best practices. Some solutions contain discussions of the language or API design decisions that led to the danger illustrated by the puzzle.

    These "lessons for language designers" are meant only as food for thought and, like other food, should be taken with a grain of salt. Language design decisions cannot be made in isolation. Every language embodies thousands of design decisions that interact in subtle ways. A design decision that is right for one language may be wrong for another.

    Many of the traps and pitfalls in these puzzles are amenable to automatic detection by static analysis : analyzing programs without running them.

    Some excellent tools are available for detecting bugs by static analysis, such as Bill Pugh and David Hovemeyer's FindBugs [Hovemeyer04]. If you are using one of these compilers, it is especially important that you not compile a puzzle until you've tried to solve it: The compiler's warning messages may give away the solution.

    The appendix of this book is a catalog of the traps and pitfalls in the Java platform. It provides a concise taxonomy of the anomalies exploited by the puzzles, with references back to the puzzles and to other relevant resources. Do not look at the appendix until you're done solving the puzzles.

    Reading the appendix first would take all the fun out of the puzzles. After you've finished the puzzles, though, this is the place you'll turn to for reference. Expressive Puzzlers The puzzles in this chapter are simple. Java Puzzlers: Traps, Pitfalls, and Corner Cases. Java Puzzlers provided in-depth explanation of traps, corner cases and pitfalls in Java programming.

    This books will determine your programming skills in Java and the core knowledge of the language. The best way to use this book is by solving the puzzles given in the book, and then only looking at the solutions provided. The book is divided into 10 chapters all of which are related with puzzlers. So, the book is all about puzzles about Java.
