4.ScheduledThreadPool
[java]
import java.util.concurrent.ScheduledExecutorService;
import java.util.concurrent.TimeUnit;
public class ThreadPoolTest {
public static void main(String[] args) {
ScheduledExecutorService schedulePool = Executors.newScheduledThreadPool(1);
// 5秒后执行任务
schedulePool.schedule(new Runnable() {
public void run() {
System.out.println("爆炸");
}, 5, TimeUnit.SECONDS);
// 5秒后执行任务，以后每2秒执行一次
schedulePool.scheduleAtFixedRate(new Runnable() {
@Override
public void run() {
System.out.println("爆炸");
}
}, 5, 2, TimeUnit.SECONDS);
}
}
ScheduledThreadPool是一个固定大小的线程池，与FixedThreadPool类似，执行的任务是定时执行。
