线程池的创建使用

public class testPool {
    public static void main(String[] args) {
        //创建服务，设置线程池大小大小
        ExecutorService service = Executors.newFixedThreadPool(10);
        //执行线程
        service.execute(new Pool());
        service.execute(new Pool());
        service.execute(new Pool());
        service.execute(new Pool());
        //关闭连接
        service.shutdown();
    }

}

class Pool implements Runnable{
    @Override
    public void run() {
        System.out.println(Thread.currentThread().getName());
    }
}
