package与import机制
基本原则:为什么需要将Java文件和类文件切实安置到其所归属之Package所对应的相对路径下。
为什么要这样做呢?如果你在程序中,用到打包命令package,并且直接编译和执行该程序。

At this writing, the release of Sun’s Java Development Kit (JDK) 1.3 is imminent, and the proposed changes for JDK 1.4 have been publicized. Although these version numbers are still in the “ones,” the standard way to refer to any version of the language that is JDK 1.2 or greater is to call it “Java 2.” This indicates the very significant changes between “old Java”—which had many warts that I complained about in the first edition of this book—and this more modern and improved version of the language, which has far fewer warts and many additions and nice designs.
This book is written for Java 2. I have the great luxury of getting rid of all the old stuff and writing to only the new, improved language because the old information still exists in the electronic 1st edition on the Web and on the CD ROM (which is where you can go if you’re stuck using a pre-Java-2 version of the language). Also, because anyone can freely download the JDK from java.sun.com, it means that by writing to Java 2 I’m not imposing a financial hardship on someone by forcing them to upgrade.
There is a bit of a catch, however. JDK 1.3 has some improvements that I’d really like to use, but the version of Java that is currently being released for Linux is JDK 1.2.2. Linux (see www.Linux.org) is a very important development in conjunction with Java, because it is fast becoming the most important server platform out there—fast, reliable, robust, secure, well-maintained, and free, a true revolution in the history of computing (I don’t think we’ve ever seen all of those features in any tool before). And Java has found a very important niche in server-side programming in the form of Servlets, a technology that is a huge improvement over the traditional CGI programming (this is covered in the “Distributed Programming” chapter).
So although I would like to only use the very newest features, it’s critical that everything compiles under Linux, and so when you unpack the source code and compile it under that OS (with the latest JDK) you’ll discover that everything will compile. However, you will find that I’ve put notes about features in JDK 1.3 here and there.
