1、程序入口:DabianTest

package com.lbh.myThreadPool.present;

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors; public class DabianTest { public static void main(String[] args) { //初始化池,并创建3条未执行任务的线程,这里new的是固定数量的线程,其他还有single,cached,schedule。
ExecutorService threadPool = Executors.newFixedThreadPool(2);
System.out.println("初始化2个坑位"); //创建需要执行的线程任务,以对象数组的形式。
DabianThread[] dabianTh = new DabianThread[5]; dabianTh[0] = new DabianThread("张三");
dabianTh[1] = new DabianThread("李四");
dabianTh[2]= new DabianThread("王五");
dabianTh[3] = new DabianThread("郑六");
dabianTh[4] = new DabianThread("黄七");
System.out.println("所有人已准备就绪"); //执行任务(即添加到池中去,由池自动调度)
for(int i = 0; i<dabianTh.length; i++){
threadPool.execute(dabianTh[i]);
try {
Thread.sleep(50);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
threadPool.shutdown();//设置执行完毕后自动关闭池
}
}

2、工作线程类:DabianThread

package com.lbh.myThreadPool.present;

/**
* 被具象化的工作线程,比如此例子中可将此类认为是厕所
*/
public class DabianThread implements Runnable {
Dabian dabian; DabianThread(String name){
dabian = new DabianImpl(name);
} public void run(){
dabian.process();
}
}

3、业务实现类:DabianImpl

package com.lbh.myThreadPool.present;

import java.text.SimpleDateFormat;
import java.util.Date; public class DabianImpl implements Dabian { String humanName;
SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss SS");// 设置日期格式 public DabianImpl(String humanName){
this.humanName = humanName;
} @Override
public void process() {
System.out.println("当前:"+humanName+"开始大便。" + sdf.format(new Date())+"坑位号:"+Thread.currentThread().getId());
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println(humanName+"大便完成。" + sdf.format(new Date())+"坑位号:"+Thread.currentThread().getId());
}
}

4、业务接口:Dabian

/**
*
*/
package com.lbh.myThreadPool.present; /**
* 大便接口,模拟多个需要大便的人,而床坑位只有有限的几个,因此采用线程池来控制需要坑位的使用。
