The Well-Grounded Java Developer: Vital techniques of Java 7 and polyglot programming Source code

Description

Manning Publications, 2012. - 496 Pages ISBN: 1617290068The Well-Grounded Java Developer offers a fresh and practical look at new Java 7 features, new JVM languages, and the array of supporting technologies you need for the next generation of Java-based software.The Well-Grounded Java Developer starts with thorough coverage of Java 7 features like try-with-resources and NIO .2. You'll then explore a cross-section of emerging JVM-based languages, including Groovy, Scala, and Clojure. You will find clear examples that are practical and that help you dig into dozens of valuable development techniques showcasing modern approaches to the dev process, concurrency, performance, and much more. Written for readers familiar with Java. No experience with Java 7 or new JVM languages required.What's Inside New Java 7 features Tutorials on Groovy, Scala, and Clojure Discovering multicore processing and concurrency Functional programming with new JVM languages Modern approaches to testing, build, and CIBen Evans is the CEO of a Java performance firm and a member of the Java Community Process Executive Committee. Martijn Verburg is the CTO of a Java performance firm, co-leader of the London JUG, and a popular conference speaker.Contentsforeword preface acknowledgments about this book about the authors about the cover illustration Developing with Java 7Introducing Java 7The language and the platform Small is beautiful—Project Coin The changes in Project Coin SummaryNew I/OJava I/O—a history Path—a foundation of file-based I/O Dealing with directories and directory trees Filesystem I/O with NIO.2 Asynchronous I/O operations Tidying up Socket-Channel functionality Summary Vital techniques Dependency InjectionInject some knowledge—understanding IoC and DI Standardized DI in Java Guice 3—the reference implementation for DI in Java SummaryModern concurrencyConcurrency theory—a primer Block-structured concurrency (pre-Java 5) Building blocks for modern concurrent applications Controlling execution The fork/join framework The Java Memory Model (JMM) SummaryClass files and bytecodeClassloading and class objects Using method handles Examining class files Bytecode Invokedynamic SummaryUnderstanding performance tuningPerformance terminology—some basic definitions A pragmatic approach to performance analysis What went wrong?
