public class TestPool {
​
    public static void main(String[] args) {
        //创建服务
        //newFixedThreadPool  参数为：线程池大小
        ExecutorService service= Executors.newFixedThreadPool(10);
        //执行
        service.execute(new Marr());
        service.execute(new Marr());
        service.execute(new Marr());
        service.execute(new Marr());
        //关闭服务
        service.shutdown();
    }
}

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