本文介绍如何利用Java 1.5以后的线程池技术来管理并发任务，通过创建固定线程池实例并提交多个Runnable任务，确保高效执行多个操作而不阻塞主线程，每个任务执行前后打印日志跟踪执行过程。

package com.thread;

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

public class ThreadTest
{
   public static void main(String[] args)
   {
       // 2个线程
       ExecutorService executorService = Executors.newFixedThreadPool(2);
       executorService.submit(new Runnable() {
           @Override
           public void run() {
               doSomeThing(1,"thread1");
           }
       });


       executorService.submit(new Runnable() {
           @Override
           public void run() {
               doSomeThing(2,"thread2");
           }
       });

       executorService.submit(new Runnable() {
           @Override
           public void run() {
               doSomeThing(3,"thread3");
           }
       });

       executorService.shutdown();
   }

   /**
   * 线程执行的方法
   * @param i
   * @param name
   */
   public static void doSomeThing(int i,String name)
   {
       System.out.println("method begin and id="+i+"threadName ="+name);
       try {
           Thread.sleep(2000);
       } catch (Exception e) {
       }
       System.out.println("method end and id="+i+"threadName ="+name);
   }
}
