This book is my new favorite Java book. This book is probably my new favorite technical book. It's simply an excellent example of what a technical reference book should be.
The first quarter of the book is a very good introduction to Java, the syntax, as well as object oriented programming (OOP). The syntax and OOP portions of the book are the best I've seen in any book. If you are new to Java, reading through these sections carefully will teach you almost everything you'll need to know about the Java language. The third edition of the book doesn't assume a C/C++ background, so even those with limited or no programming experience will find this section very helpful.
Next you'll find excellent coverage of the Java platform. The bulk of the book is a reference of the different Java classes in JDK 1.0, 1.1, 1.2, and even 1.3Beta. The coverage is excellent. I would have liked to see examples, but I suppose that really is asking too much from one book.
I have a large library of Java books, but this one is #1 for me. Shelf time for this book is going to be very low. The book literally hasn't seen a shelf since it arrived from Amazon.
There are several Java books I find to be far superior to others. For anyone new to the Java language, I believe the following are the very best books to have nearby (ranked in order): Java in a Nutshell, 3rd... Java Examples in a Nutshell... Java Foundation Classes in a Nutshell... Java Enterprise in a Nutshell... The Java Class Libraries, 2nd, Vol 1. by Patrick Chan
Obviously, I'm a fan of David Flanagan's Java books (he wrote the top four). Pick one up to see why. They are all excellent, but my favorite is this one (JavaNut 3rd edition). The set of four Flanagan books easily comprise the best resource on Java available.

There have been three editions of this book, all of them excellent reference books but too condensed to be great tutorials.
The first edition had everything you needed to know about Java 1.0, including AWT (the GUI) descriptions and example programs; but a lot has changed since Java 1.0, which is basically only good for writing applets. Still, many browsers can only handle Java 1.0.
The second edition covered Java 1.1 and the AWT, but the examples were split off into a second book, "Java Examples in a Nutshell." IMHO the second edition is the best single-source reference book.
Much has been added in Java 1.2/1.3, but the Java 1.1 basics have not changed. This third edition further splits off the GUI information (including the new Swing classes) into "Java Foundation Classes in a Nutshell," and as such cannot stand on its own for GUI programming. Enterprise programming is also split off. For what it covers, each edition keeps getting better, but also narrows its coverage.
While the book is an excellent reference, a paper reference is no longer the best programming support. Once you have learned Java basics, the best way to program is with Sun's online documentation open on your desktop--IF you have a fast internet connection or can download the whole thing to your hard drive. You get faster lookup and detailed descriptions of every method, rather than just lists of methods.
Bottom line: a great book, but consider carefully whether its coverage meets your needs.

I experienced this book at two different levels. As a beginner this guide took me through the syntax and concepts while I was studying the language. At a later stage this book was used as my reference material. Without any hesitation I have to say that this book is my Java Bible!
Like most reference guides, the beginning of this book will give you an introduction to the language. However it is definitely not a tutorial for those who are unfamiliar to the Java language, but rather a quick reference to remind programmers why certain concepts are in place within the Java language. If you forgot how or why to cast data, you can find it right here. This part of the book can also be used by C++ programmers to understand the differences between the two languages.
This book is loaded with information regarding the language. APIs, methods, tools and mechanisms are all covered with numerous short examples that demonstrate how to perform common tasks with the classes and interfaces that comprise the Java Platform.
Throughout my studies I had many questions regarding Java, but "Java in a Nutshell" never left me in the dark. I didn't need any other books, and I am sure I never will. Thank you Tim O'Reilly for giving us David Flanagan, and thank you David Flanagan for giving us, Java geeks, our own Bible.

If you liked the first version of this book, you'll love the update!

As in the first ediiton, they have most of the Java package API's (see the end of the review) listed in the back along with an object model for each package.

The real value of the book lies in the front half, offering complete and consise descriptions of the changes in the JDK 1.1, so you can quickly glean what is new to the language.

Additionally, it offers sections on some of the newer features/API's such as JavaBeans, Reflection, Serialization, and so forth, even a quick comparison of the old and new event models with the return of the Scribble applet. Older sections on Applets, Java Syntax, and other categories are back and have been updated as well.

This book is a great Java 1.1 reference - it offers just enough depth beyond the online HTML documentation to make it an excellent source for a quick overview or refresher. It's not a book to learn Java from - but it should be the second book you buy. I can think of no better book to help in the migration from JDK 1.02 to JDK 1.1 development.

The only downside is a lack of JDBC, RMI, and security overviews (or package API's in the back!), which the book said would be covered in "Java Enterprise in a Nutshell".

Die Computer - Bücher der "In A Nutshell" - Serie aus dem O' Reilly - Verlag sind in erster Linie als Referenz gedacht, die man bei der täglichen Arbeit mit der behandelten Programmiersprache zum Nachschlagen von Kommandos bzw. deren Syntax verwendet. Dennoch enthalten diese Titel auch sehr gute Einführungskapitel. Reine Tutorials bieten sie nicht, dafür sind sie auch noch nützlich, wenn man die Einarbeitungsphase hinter sich gelassen hat. Somit gehören die "In A Nutshell" - Titel zu den wenigen Büchern, die sich zu Recht sowohl an Anfänger als auch an fortgeschrittene Anwender richten. JAVA In A Nutshell neben einer alphabetischen Auflistung der Klassen, geordnet nach Paketen, (Quick Reference) enthält das Buch einführende Kapitel unter anderem zu den Themen Applets, Events, Tools usw. Das Buch gibt es auch in einer deutschen Übersetzung. Es ist aber in der englischen Version sehr verständlich geschrieben und auf den Punkt gebracht. In didaktischer Hinsicht sind Bücher aus dem englisch - sprachigen Raum oft immer noch überlegen, was eventuelle Sprachschwierigkeiten meist mehr als kompensiert. (Dies ist eine Amazon.de an der Uni-Studentenrezension.)

This book does a great job of getting a C/C++ programmer into doing Java programming. In addition, it has some really useful information about the Java 1.1 enhancements. For the most part, I really enjoyed it (although it would not be good for a beginning programmer).
On the other hand, the desktop reference is weak. For each method of a class, it is unclear 1) exactly what the purpose of the method is and 2) exactly what the arguments are for. This makes the reference less than wonderful. If you have the Sun references readily available on-line, this isn't too big a limitation, and it's nice to be able to find each class listed in a very concise manner. The information about what's new and what's deprecated (obsolete) in 1.1 is also very useful.
In general, I like this book a lot, and I keep it near me when I'm doing Java coding, but I find that I also need another reference nearby. I don't do enough Java coding to be able to get away with just the brief descriptions in the reference section. On the other hand, it's the best place to go for an overview of what methods and variables are available in a class.

Java in a Nutshell ist ein sehr gutes Nachschlagewerk für Klassenbibliotheken in Java. Es soll Java Neulingen zwar einen schnellen Einstieg verschaffen, aber dies ist nur für C oder C++ erfahrene Menschen möglich und das ist auch die große Schwäche dieses Buches. Das Buch wendet sich fast nur an C und C++ erfahrene Programmieren. Es vergleicht Java mit C und versucht teilweise Java Begriffe mit C Begriffen zu erklären. Jemand der keine Erfahrung mit C hat, ist dann leider aufgeschmissen. Ich benutze dieses Buch nur zum nachschlagen, wenn ich eine Klassenbibliothek suche oder ich einen Befehl brauche. Ansonsten ist dieses Buch leider nicht sehr gut zu benutzen. Es gibt fast keine Programmbeispiele, an denen man sehen kann, wie ein Befehl benutzt wird und leider auch fast keine Erklärungen zu den Klassenbibliotheken und den Befehlen. Dieses Buch ist sehr nützlich zum Nachschlagen, in dem Punkt ist es fast unschlagbar, aber zum Java lernen oder zum Befehlssyntax nachschlagen ist es völlig ungeeignet.

Imagine going to the awesome javasoft website and compressing it into 500-odd pages. This is Java in a Nutshell.
As a programmer who needs classes and methods at my fingertips, I don't want to be forever logged into the Sun site to get hold of code. For me using VJava, DB2, Lotus Notes etc, to keep Netscape open permanently slows me down. I want to see code in concise paper form for perusing and for adding post-it notes to useful pages.
This book is a good physical size, about the size of a good novel, and thus is refreshingly concise. You genuinely can put it on your desk without it becoming a 'conversation piece'. It doesn't come with code cheats. For that I use and recommend 'The Complete Reference' which is the size of a squashed brick.
Four stars because IMHO, this reference could do without a 'What is Java' introduction (even though it's a small part of the book) - it's better done in any textbook.

ISBN 156592262X or 1565923049 for the deluxe CD version. This is David Flanagan's classic text on Java published by O'Reilly. It is for experienced programmers new to Java, not new to programming. It covers the Java language and lists all the methods of the standard classes, indexed in a variety of convenient ways. Unfortunately there is no room to provide anything you could not find out by looking at the JavaDOC. It would be nice, if at least on the CD, there were additional notes about the various gotchas, how the various methods are used together etc. It is a reference, not a tutorial. It comes in two versions, plain and deluxe with CD that includes four other books: Exploring Java, the Java Language Reference, Java Fundamental Classes Reference, and the Java AWT Reference. The author answers his email and uses the feedback to improve the book.

This book is good for what it was intented: a reference.
It rapidly speeds through the essentials of the language, providing simple examples to demonstrate concepts. The remainder of the book provides a reference to the core Java classes.
I was initially sceptical of the number of pages dedicated to reprinting what was already available online. However, this section has proven invaluable as I have found it significantly faster and easier to use than the online equivalents. Once the appropriate class has been found the online documentation can be used to find any further details required.
The book is not overburdened with large examples or long winded explanations. This means finding things quickly, and also makes it easy to carry around (you never know when you might need it :-)
