本文整理了Java中java.util.concurrent.ThreadPoolExecutor.getTask()方法的一些代码示例，展示了ThreadPoolExecutor.getTask()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。ThreadPoolExecutor.getTask()方法的具体详情如下：
包路径：java.util.concurrent.ThreadPoolExecutor
类名称：ThreadPoolExecutor
方法名：getTask

ThreadPoolExecutor.getTask介绍

[英]Performs blocking or timed wait for a task, depending on current configuration settings, or returns null if this worker must exit because of any of: 1. There are more than maximumPoolSize workers (due to a call to setMaximumPoolSize). 2. The pool is stopped. 3. The pool is shutdown and the queue is empty. 4. This worker timed out waiting for a task, and timed-out workers are subject to termination (that is, allowCoreThreadTimeOut || workerCount > corePoolSize) both before and after the timed wait, and if the queue is non-empty, this worker is not the last thread in the pool.
[中]根据当前的配置设置，对任务执行阻塞或定时等待，或者如果由于以下任何原因必须退出此工作进程，则返回null:1。有超过maximumPoolSize的工作人员（由于调用了setMaximumPoolSize）。2.游泳池停了。3.池已关闭，队列为空。4.此工作线程在等待任务时超时，超时工作线程在超时等待前后都会被终止（即allowCoreThreadTimeOut | | workerCount>corePoolSize），如果队列非空，则此工作线程不是池中的最后一个线程。
