}
示例2: test_DelayQueue_past_order
import java.util.concurrent.DelayQueue; //導入方法依賴的package包/類
@Test
public void test_DelayQueue_past_order(){

示例4: main
import java.util.concurrent.DelayQueue; //導入方法依賴的package包/類
public static void main(String[] args) {
// 創建延時隊列
DelayQueue<Message> queue = new DelayQueue<Message>();
// 添加延時消息,m1 延時3s
Message m1 = new Message(1, "world", 3000);
// 添加延時消息,m2 延時10s
Message m2 = new Message(2, "hello", 1000);
//將延時消息放到延時隊列中
queue.offer(m2);
queue.offer(m1);
// 啟動消費線程 消費添加到延時隊列中的消息，前提是任務到了延期時間
ExecutorService exec = Executors.newFixedThreadPool(1);
exec.execute(new Consumer(queue));
exec.shutdown();
}
示例5: replace
