ExecutorService 用例

1. import java.util.concurrent.ExecutorService;
2. import java.util.concurrent.Executors;
3. public class TestCachedThreadPool{
4. public static void main(String[] args){
5. ExecutorService executorService = Executors.newCachedThreadPool();
6. //      ExecutorService executorService = Executors.newFixedThreadPool(5);
7. //      ExecutorService executorService = Executors.newSingleThreadExecutor();
8. for (int i = 0; i < 5; i++){
9. executorService.execute(new TestRunnable());
10. System.out.println("************* a" + i + " *************");
11. }
12. executorService.shutdown();
13. }
14. }
15. class TestRunnable implements Runnable{
16. public void run(){
17. System.out.println(Thread.currentThread().getName() + "线程被调用了。");
