多线程22：线程池

 1 package com.thread.gaoji;
 2 
 3 import java.util.concurrent.ExecutorService;
 4 import java.util.concurrent.Executors;
 5 
 6 //测试线程池
 7 public class TestPool {
 8 
 9     public static void main(String[] args) {
10         //1.创建服务，创建线程池
11         //newFixedThreadPool(10); 参数为线程池的大小
12         ExecutorService service = Executors.newFixedThreadPool(10);
13 
14         //执行
15         service.execute(new MyThread());
16         service.execute(new MyThread());
17         service.execute(new MyThread());
18         service.execute(new MyThread());
19 
20         //2.关闭连接
21         service.shutdown();
22     }
23 }
24 
25 class MyThread implements Runnable {
26 
27     @Override
28     public void run() {
29         System.out.println(Thread.currentThread().getName());
30     }
31     
32 }
33 
34 结果：
35 pool-1-thread-2
36 pool-1-thread-3
37 pool-1-thread-1
38 pool-1-thread-4
