public class Test {
public static void main(String[] args) {
//创建一个线程池,它可安排在给定延迟后运行命令或者定期地执行。
ScheduledExecutorService pool = Executors.newScheduledThreadPool(2);
//创建实现了Runnable接口对象,Thread对象当然也实现了Runnable接口
Thread t1 = new MyThread();
Thread t2 = new MyThread();
Thread t3 = new MyThread();
Thread t4 = new MyThread();
Thread t5 = new MyThread();
//将线程放入池中进行执行
pool.execute(t1);
pool.execute(t2);
pool.execute(t3);
//使用延迟执行风格的方法
pool.schedule(t4, 10, TimeUnit.MILLISECONDS);
pool.schedule(t5, 10, TimeUnit.MILLISECONDS);
//关闭线程池
pool.shutdown();
}
}
class MyThread extends Thread {
@Override
public void run() {
System.out.println(Thread.currentThread().getName() + "正在执行。。。");
}
