示例1: testPurge

import java.util.concurrent.ScheduledThreadPoolExecutor; //導入方法依賴的package包/類
/**
 * purge eventually removes cancelled tasks from the queue
 */
public void testPurge() throws InterruptedException {
    final ScheduledFuture[] tasks = new ScheduledFuture[5];
    final Runnable releaser = new Runnable() { public void run() {
        for (ScheduledFuture task : tasks)
            if (task != null) task.cancel(true); }};
    final ScheduledThreadPoolExecutor p = new ScheduledThreadPoolExecutor(1);
    try (PoolCleaner cleaner = cleaner(p, releaser)) {
        for (int i = 0; i < tasks.length; i++)
            tasks[i] = p.schedule(new SmallPossiblyInterruptedRunnable(),
                                  LONG_DELAY_MS, MILLISECONDS);
        int max = tasks.length;
        if (tasks[4].cancel(true)) --max;
        if (tasks[3].cancel(true)) --max;
        // There must eventually be an interference-free point at
        // which purge will not fail. (At worst, when queue is empty.)
        long startTime = System.nanoTime();
        do {
