内容简介
编程和测试经常被认为是两个不同的领域。在本书中，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代码是如何在JVM中运作的，以及如何调优性能。
通过本书，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。开发人员和性能工程师等也能够学到多种用来改进Java 7和Java 8应用程序性能的特性，工具和处理方法。
作者简介
Scott Oaks是Oracle公司的架构师，主要负责Oracle中间件软件的性能。他在1987年被Sun Microsystems公司雇用成为一名Java的传播者，并在2001年加入了该公司的Java性能组，这也是他现在的关注重点。Scott编写了O’Reilly出版社的多本有关Java安全、Java线程和Jini方面的书籍。
