JAVA中只要有一个线程执行成功，就算执行成功 如何写代码

• java

类似于前端中的Promise.race([p1,p2,p3...])

使用CountDownLatch

package CountDownLatch;

import java.util.concurrent.CountDownLatch;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

public class CountDownLatchTest {
	public static void main(String[] args) {

		ExecutorService es = Executors.newFixedThreadPool(10);
		CountDownLatch latch = new CountDownLatch(1);
		for (int i = 0; i < 10; i++) {
			es.submit(() -> {
				try {
					long wait = (long) (Math.random() * 1000);
					Thread.sleep(wait);
					System.out.println(wait);
					latch.countDown();
				} catch (InterruptedException e) {
					Thread.currentThread().interrupt();
				}
			});
		}

		// wait for the latch to be decremented by the fast threads
		try {
			latch.await();
			System.out.println("Fast Thead End");
			es.shutdownNow();

		} catch (InterruptedException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

}
