This book is for developers who want to become proficient with Java EE 8 for their enterprise application development. Basic knowledge of Java is assumed.

多年以来，函数式编程被认为是少数人的游戏，不适合推广给普罗大众。写作此书的目的就是为了挑战这种思想。本书将探讨如何编写出简单、干净、易读的代码；如何简单地使用并行计算提高性能；如何准确地为问题建模，并且开发出更好的领域特定语言；如何写出不易出错，并且更简单的并发代码；如何测试和调试Lambda表达式。如果你已经掌握Java SE，想尽快了解Java 8新特性，写出简单干净的代码，那么本书不容错过。

●本书是作者多年来教学实践经验的总结，汇集了学员在学习课程或认证考试中遇到的概念、操作、应用等问题及解决方案 ●针对Java SE 8新功能全面改版，无论是章节架构或范例程序代码，都做了重新编写与全面翻新 ●详细介绍了JVM、JRE、Java SE API、JDK与IDE之间的对照关系 ●从Java SE API的源代码分析，了解各种语法在Java SE API中的具体应用 ●提供练习的Lab操作文档，方便读者掌握练习重点 ●将IDE操作纳入教学内容使读者能与实践结合，提供视频教学能更清楚地帮助读者掌握操作步骤
