Next, you almost copy the exact same structure for the next thread pool class, DatamineThread.
接下来，对于另一个线程池类DatamineThread，几乎复制了完全相同的结构。
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.
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。
Each worker thread performs some bit of work using the TaskHandler class.
每个工作者线程使用taskhandler类执行一部分工作。
When the bot is used, this property is read and each custom class is run as a thread of the main Watchit bot.
当使用bot时，该属性会被读取且每个自定义类作为主watchit bot的一个线程运行。
You don't call the ThreadPoolExecutor constructor directly to create a thread pool but instead use the Executors utility class to create one.
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。
This constructor lets you specify the priority, memory sizes, and period for a thread, along with the class that represents the thread to be run (a class that extends PeriodicThread).
此构造函数让您能够指定优先级、内存大小、线程周期和表示要运行的线程的类(扩展periodicthread的类)。
In the constructor of StockQuoteGenerator class, which is a singleton class, we are starting a new thread and assigning a Runnable object to that thread.
在stockquotegenerator类(一个单态类)的构造函数中，我们启动了一个新线程，并向该线程分配了一个Runnable对象。
The PresentationReconciler class updates the text's appearance with every keystroke, and the Reconciler class runs in a daemon thread, parsing the document without holding up the user interface (UI).
presentationreconciler类根据每次击键更新文本的外观，而Reconciler类运行一个守护线程，不必将用户界面(UI)挂起就能解析该文档。
Class initialization Any type of regular or real-time thread can initialize a class, including a NHRT, which can cause unexpected MemoryAccessError.
