The 3rd edition of the well-known reference, Java in a Nutshell, covers the essential APIs of Java 1.2, including networking, security, input and output, and basic language and utility classes. Due to the size of the Java 1.2 API, graphics and graphical user interface classes are now examined in a volume called Java Foundation Classes in a Nutshell, and server-side and enterprise programming are detailed in Java Enterprise in a Nutshell.
Though primarily a reference, the book starts off with a thorough, fast-paced introduction to Java, exploring all the key topics, including syntax, object-oriented programming, security, beans, and tools. These discussions are brief and very information-dense, and if you are buying this book to learn the language, you will probably be overwhelmed by the speed of this initiation.
This book intends to document quite a bit of Java, and it easily succeeds with broad coverage of Java programming in Part I, and API cataloging broken down by package in Part II. For example, discussions in Part I explain Types, Reflection, and Dynamic Loading. The handling of these topics takes a little over a page, but the book gives a useful overview with code examples that clearly illustrate the points made. It is one of the clearest and most concise treatments of these three topics available.
The chapters in Part II include an introduction, diagrams, and sections for each class in the package. The sections for each class can be very informative, as in the discussion of the Socket class in the java.net chapter, which includes how to instantiate a Socket object, getting I/O streams from the object you instantiated, and how to alter the behavior of sockets. This discussion, like most in this book, is brief, clear, and to the point.
If you are looking for a Java reference, this is a solid volume that will provide lasting value. --John Keogh

O'Reilly books are rarely for neophytes, but advanced users swear by them, and these will be no exception. Englander covers a hot Java subtopic for students, programmers, and professionals already familar with Java and object-oriented programming. He discusses events, event adapters, properties, persistence, java archive files, the BeanBox tool, property editors, ActiveX, and the java.beans Package. Flanagan's work is the book Java programmers want nearby when they are at the keyboard. A complete ready-reference work, this belongs in all collections supporting programmers. Java is a constantly changing language so Nutshell will be coming out often with new editions; always have the newest one on hand. Reese goes beyond simple applet design to relational databases, SQL, object-oriented database applications, application servers, and remote object manipulation. The examples used throughout the book are based on a banking application designed in Java.
