说明：  本书旨在帮助您充分利用了Java™ 最有效地利用 编程语言，其基本库，java.lang中，java.util中， 并在较小程度上的java.util.concurrent和java.io.该书论述 不时，但不包括图形用户界面的其他库 规划，企业宣传短片，或移动设备。 这本书由七八项，其中每个传达一个规则。 这些规则一般认为是捕捉有益的做法是最好的和最 有经验的程序员。这些项目是松散分为十章，每 关于软件设计的一个广泛的方面。这本书是不是拟 从头到尾阅读：每个项目都是独立的，或多或少。这些项目是 大量交互参照，因此您可以轻松地通过这本书绘制自己的道路。 许多新的功能被添加到该平台在Java5（版本1.5）。大部分 在这本书中的项目以某种方式使用这些功能。下表显示 你去哪里这些功能的主要内容：
(THIS book is designed to help you make the most effective use of the Java™ programming language and its fundamental libraries, java.lang, java.util, and, to a lesser extent, java.util.concurrent and java.io. The book discusses other libraries from time to time, but it does not cover graphical user interface programming, enterprise APIs, or mobile devices. This book consists of seventy-eight items, each of which conveys one rule. The rules capture practices generally held to be beneficial by the best and most experienced programmers. The items are loosely grouped into ten chapters, each concerning one broad aspect of software design. The book is not intended to be read from cover to cover: each item stands on its own, more or less. The items are heavily cross-referenced so you can easily plot your own course through the book. Many new features were added to the platform in Java 5 (release 1.5). Most of the items in this book use these features in some way. The followin)
