ExecutorService测试06

package t1;

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

public class TestThread18 {

public static void main(String[] args) {
System.out.println(TimeUnit.DAYS.toHours(1));// 24
System.out.println(TimeUnit.HOURS.convert(1, TimeUnit.DAYS));// 24
ExecutorService es = Executors.newSingleThreadExecutor();
for (int i = 0; i < 5; i++) {
final int index = i;
es.execute(new Runnable() {
public void run() {
System.out.println(index);
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
});
}
}
}

结果：

 任务执行完成后程序不会结束。
