ThreadPoolExample.main(ThreadPoolExample.java:26) 可以看出当第 6 个任务来的时候,线程池则执行了 AbortPolicy 拒绝策略,抛出了异常。因为队列最多存储 2 个任务,最大可以创建 3 个线程来执行任务(2+3=5),所以当第 6 个任务来的时候,此线程池就“忙”不过来了。 自定义拒绝策略 自定义拒绝策略只需要...

还可以根据需要调用其他Thread方法来设置线程的优先级、守护状态等属性。如下是CustomThreadFactory的使用方法，如下：import java.util.concurrent.ThreadPoolExecutor; import java.util.concurrent.TimeUnit; import java.util.concurrent.SynchronousQueue; publicclassThreadPoolExample{ publicstaticvoidmain(String[] ...
