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
Topics covered: Part I, "Introducing Java," provides broad coverage of Java programming topics, including data types, syntax, classes, and objects; Java file structure; inner classes; interfaces; packages; creating and initializing objects; destroying and finalizing objects; input/output; cryptography; networking; security; threads; JavaBeans; JavaDoc; and tools that come with Java 1.2 SDK.
Part II, "The Java API Quick Reference," includes chapters on the following Java packages: java.beans, java.beans.beancontext, java.io, java.lang, java.lang.ref, java.lang.reflect, java.math, java.net, java.security, java.security.acl, java.security.cert, java.security.interfaces, java.security.spec, java.text, java.util, java.util.jar, java.util.zip, javax.crypto, javax.crypto.interfaces, javax.crypto.spec, and a final chapter, which provides an index for classes, methods, and fields.
This bestselling quick reference contains an accelerated introduction to the Java language and its key APIs, so seasoned programmers can start writing Java code right away. The third edition of Java in a Nutshell covers Java 1.2 and Java 1.3 beta and includes:
- A description of the syntax of the Java language, written in a tight, concise style, that can serve as both a fast-paced tutorial and a language reference.
- An explanation of the object-oriented features of Java that does not assume any prior object-oriented programming experience.
- An overview of the essential Java APIs that shows how to perform common tasks, such as string manipulation, input/output, and thread handling, with the classes and interfaces that comprise the Java 2 platform.
- Documentation for the Java development tools shipped with Sun's Java SDK.
This book also includes O'Reilly's classic-style, quick-reference material for all of the classes in the essential Java packages, including java.lang, java.io, java.beansjava.math, java.net, java.security,java.text, java.util, and javax.crypto. This reference material covers all of the new classes in Java 1.2 and 1.3. Once you've learned Java, you'll keep this book next to your keyboard for handy reference while you program.
This book is part of the two-volume set of quick references that every Java programmer needs. It is an essential companion to Java Foundation Classes in a Nutshell, which covers the graphics and graphical user interface APIs in the Java 2 platform, including Swing, AWT, and Java 2D. A third volume, Java Enterprise in a Nutshell, focuses on the Java Enterprise APIs and is of interest to programmers working on server-side or enterprise Java applications.
