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...

, summing them up in the reduce call. this simple example may not demonstrate the full usefulness of using a custom thread pool, but the benefits become obvious in situations where we do not want to tie-up the common thread pool with long-running tasks – such as processing data from a ...
