Java concurrency线程池之线程池原理(二)_动力节点Java学院整理

线程池示例

在分析线程池之前，先看一个简单的线程池示例。

import java.util.concurrent.Executors;import java.util.concurrent.ExecutorService;public class ThreadPoolDemo1 {  public static void main(String[] args) {    // 创建一个可重用固定线程数的线程池    ExecutorService pool = Executors.newFixedThreadPool(2);    // 创建实现了Runnable接口对象，Thread对象当然也实现了Runnable接口    Thread ta = new MyThread();    Thread tb = new MyThread();    Thread tc = new MyThread();    Thread td = new MyThread();    Thread te = new MyThread();    // 将线程放入池中进行执行    pool.execute(ta);    pool.execute(tb);    pool.execute(tc);    pool.execute(td);    pool.execute(te);    // 关闭线程池    pool.shutdown();  }}class MyThread extends Thread {  @Override  public void run() {    System.out.println(Thread.currentThread().getName()+ " is running.");  }}
