实现代码

public class TestPool {       public static void main(String[] args) {           //1.创建服务，创建线程池        //newFixedThreadPool 参数为：线程池大小        ExecutorService service = Executors.newFixedThreadPool(10);        //执行        service.execute(new MyThread());        service.execute(new MyThread());        service.execute(new MyThread());        service.execute(new MyThread());        //关闭连接        service.shutdown();    }}class MyThread implements Runnable{       @Override    public void run() {           for (int i = 0; i < 100; i++) {               System.out.println(Thread.currentThread().getName());        }    }}

参数10为线程池的最大线程数

ExecutorService service = Executors.newFixedThreadPool(10);

用完之后记得关闭连接

service.shutdown();
