清单 3 中的代码展示了用多线程加以说明的和清单 1 相同的问题。

The code in Listing 3 exhibits the same problem as demonstrated with multiple threads and Listing 1.

这种并行性（或多线程）问题在于确保您希望为其更新信息的线程，仅影响正在处理的数据和信息。

This issue with concurrency (or multi-threading) is ensuring that threads that you want to update the information with only affect the data and information you are processing.

可以用它们来解决普通的和高级的并发性问题，现在应当可以让您开始编写所喜爱(也没有错误)的多线程程序了。

They can be used to resolve both normal and advanced concurrency issues and should get you started writing pain-free (as well as error-free!) multithreaded programs.
