编码和测试经常被认为是两个不同的专业领域。
　　在《Java性能权威指南（英文 影印版）》中，作为Java专家的作者Scott Oaks阐述了任何一个使用Java的人都应该深入了解的代码是如何在JVM中运作的，以及如何调优性能。
　　通过《Java性能权威指南（英文 影印版）》，你将深入掌握包括Java应用性能，使用Java虚拟机（JVM）和Java平台以及语言和API方面的知识。通过这本综合指南，开发人员和性能工程师等也能够学到多种用来改进Java7和Java8应用程序性能的特性、工具和处理方法。
　　运用四种规则从性能测试中获取最佳结果；
　　使用JDK工具来收集Java应用程序的运行信息；
　　了解使用JIT编译器的优点和缺点；
　　调整JVM垃圾收集器来尽可能减少对程序的影响；
　　使用特别技术来管理堆内存和JVM本地内存；
　　最大化Java线程处理和同步性能特性；
　　在JavaEE和JavaSEAPI中处理性能问题；
