由于文档对chat机制介绍不多，因此它是进一步了解代码的很好起点。
As the chat mechanism is only lightly covered in the documentation, it's a good starting point for further code exploration.
清单1是相关代码和第一个测试(您一定明白编写单元测试的重要性，这里就不多说了)。
Listing 1 contains the code, as well as my first test. (I hope I don't need to convince you of the value of writing unit tests.)
RP使用的代码基本上与在 第 1部分 中看到的代码差不多，关于 RP内部原理的更多信息参见第 1 部分。
The code that the RP uses is essentially just like the code you saw in Part 1, so I refer you there for more information about RP internals.
另一方面，如果测试代码要进行对象分配工作(差不多所有的代码都要这样)，那么垃圾收集器也肯定会运行。
On the other hand, if the test code does any object allocation at all (and nearly all code does), it's going to create garbage, and eventually, the garbage collector is going to have to run.
只写你需要写的代码，绝不多写。结果你的应用将更加精简和健康。
Write just the code you need and no more. Your app will be leaner and healthier as a result.
尽管它们通常很快，但仍然需要差不多一秒钟的时间来把你的源代码编译成CSS，而你不得不等待这段时间才能预览到代码的效果。
Even though they are generally fast, it still takes a second or so to compile your code to CSS, which you have to wait for before previewing its result.
Hello实用工具内容并不多，但是对于研究JAR文件却是一个很有用的“脚手架”，我们先从执行此代码开始。
The Hello utility isn't much, but it's a useful scaffold for exploring JAR files, starting with executing the code.
但是它是一个良好的开始，并且向您展示了，用不多的XQuery代码，就可以得到一组基本的描述文档文本内容特征的关键词。
But it's a good start and shows you that with a small amount of XQuery, it's possible to get a basic set of keywords characterizing a document's textual content.
他们带着很多理论知识(其中一些是好的且有帮助的)离开了学校，但是对于如何编写好的代码却所知不多。
They come out of college knowing lots of theory (some of it good and helpful) but not very much about how to write good code.
允许您使用这么少的代码行创建如此复杂的GUI程序的编程语言并不多见。
Not many programming languages enable you to create such a complex GUI program in so few lines of code.
如果您对命令行接口使用得不多的话，这段代码看上去可能有点令人生畏。
This code might look a bit daunting if you haven't used the command-line interface much.
