Focusing on the intersection of coding and testing, this practical guide emphasizes the importance of understanding Java code behavior within the Java Virtual Machine. Scott Oaks, a Java expert, provides insights into performance tuning and optimization. The updated second edition offers comprehensive knowledge for anyone working with Java, equipping readers with the skills to enhance application performance effectively.
Scott Oaks, lead author of O'Reilly's new JXTA in a Nutshell, emphasizes that fundamental scalability and centralization forces are limiting the Internet's growth. Peer-to-peer networks like JXTA are crucial for advancing the Internet's scalability, management, and security, enabling unrestricted information exchange among peers and accommodating new consumer devices. Written by key members of Sun Microsystems' Project JXTA, this work serves as the definitive reference for the most robust platform for Peer-to-Peer distributed computing. P2P allows users with the same networking application to connect and access files directly from each other's hard drives, marking a significant advancement in P2P technology.
O'Reilly's pioneering reference provides comprehensive information for getting started, including an overview of P2P distributed computing, details about the JXTA Project's platform, and guidance for developers wishing to contribute to the effort. It introduces major concepts in a practical manner, explaining them in the context of the shell, and includes a complete reference to the JXTA application bindings, along with the full JXTA protocol specification. The book also addresses critical topics such as security and the integration of JXTA technology with standard Java classes.
Revised to cover Java 1.2, this text examines Java's thread facilities showing: where to use threads to increase efficiency, how to use them effectively, and how to avoid common mistakes. It covers the Thread and ThreadGroup classes, the Runnable interface, and the language's synchronized operator.
Jini is a simple set of Java Classes and services that allows devices (e.g., printers) and services (e.g., printing) to access each other seamlessly, adapt to a continually changing environment, and share code and configurations transparently. Jini has the potential to radically alter our use of computer networks, since it allows and encourages totally new types of services and new uses of existing networks. Jini in a Nutshell is a quick reference guide to developing services and clients using Jini. It covers everything an experienced Java programmer needs to know to implement Jini, including tutorial chapters to get you up to speed quickly and reference chapters that analyze and explain every Java package related to Jini. Over the course of the book the authors develop a complete example program--with samples of both server and client applications.Topics covered Jini in a Nutshell covers the Jini 1.0 specification and requires the Java 2 Platform.
Java Security is an in-depth exploration aimed at developers, network administrators, and anyone who needs to work with or understand Java's security mechanisms. It discusses in detail what security means and doesn't mean, what Java's default security policies are, and how to create and implement your own policies
Coding and testing are often considered separate areas of expertise. In this comprehensive guide, author and Java expert Scott Oaks takes the approach that anyone who works with Java should be equally adept at understanding how code behaves in the JVM, as well as the tunings likely to help its performance. You'll gain in-depth knowledge of Java application performance, using the Java Virtual Machine (JVM) and the Java platform, including the language and API. Developers and performance engineers alike will learn a variety of features, tools, and processes for improving the way Java 7 and 8 applications perform. Apply four principles for obtaining the best results from performance testing Use JDK tools to collect data on how a Java application is performing Understand the advantages and disadvantages of using a JIT compiler Tune JVM garbage collectors to affect programs as little as possible Use techniques to manage heap memory and JVM native memory Maximize Java threading and synchronization performance features Tackle performance issues in Java EE and Java SE APIs Improve Java-driven database application performance
