《Java开发手册》四年前首次发布,到现在共有200多万开发者下载阅读,并用于实际开发中。此次嵩山版增加了前后端规约,并且修正了泰山版出现的一些问题。 内容变化: ①增加前后端规约。打通前后端的任督二脉,形成前后端协作开发的共识。 ②重画分层图例。新图更加突出分层的清晰度,并且去掉图中有歧义的向上箭头。 ③修正BigDecimal的equals错误。3.0与3.00在我们的常规认知里是相等的,但是equals比较的结果由于考虑到精度因素,所以返回为false。 ④修正泰山版的部分文字描述错误。

☆ 资源说明:☆ [奥莱理] Java 性能优化 权威指南 (英文版) [奥莱理] Java Performance The Definitive Guide (E-Book) ☆ 图书概要:☆ 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. ☆ 出版信息:☆ [作者信息] Scott Oaks [出版机构] 奥莱理 [出版日期] 2014年05月01日 [图书页数] 426页 [图书语言] 英语 [图书格式] PDF 格式
