分析这段代码时您可以看到，我们添加了另一个队列实例，然后将该队列传递给第一个线程池类ThreadURL。
In looking at the code, you can see that we added another instance of a queue, and then passed that queue into the first thread pool class, ThreadURL.
每个工作者线程使用taskhandler类执行一部分工作。
Each worker thread performs some bit of work using the TaskHandler class.
使用Executors工具类来创建线程池，而不是直接调用ThreadPoolExecut or构造器来创建。
You don't call the ThreadPoolExecutor constructor directly to create a thread pool but instead use the Executors utility class to create one.
Handler类允许您在线程之间协调和通信。
The android.os.Handler class allows you to coordinate and communicate between threads.

You could accumulate debugging information in a thread-local container as shown by the DebugLogger class in Listing 4.
Volta类库不支持多线程。
另一个常见的线程模型是为某一类型的任务分配一个后台线程与任务队列。
Another common threading model is to have a single background thread and task queue for tasks of a certain type.
有些类保留从一个方法调用到下一个方法调用的状态信息，要在实践中使这样的类成为线程安全的是困难的。
Some classes retain state information from one method invocation to the next, and it is difficult to make such classes thread-safe in any practical way.
它常常是把有状态类描绘成线程安全的，或者封装非线程安全类以使它们能够在多线程环境中安全地使用的最容易的方式。
It is often the easiest way to render a stateful class thread-safe, or to encapsulate non-thread-safe classes so that they can safely be used in multithreaded environments.
有时，要在不影响类的功能、易用性或性能的情况下使类成为线程安全的是很困难的。
Sometimes, it is very difficult to make a class thread-safe without compromising its functionality, ease of use, or performance.
非线程安全类通常可以安全地在多线程程序中使用，只要您能确保一个线程所用的类的实例不被其它线程使用。
A class that is not thread-safe can often be used safely in a multithreaded program as long as you ensure that instances of that class used by one thread are not used by other threads.
