工厂模式是最常用的模式之一，在创建线程的时候，我们当然也能使用工厂模式来生产Thread，这样就能替代默

认的new THread，而且在自定义工厂里面，我们能创建自定义化的Thread，并且计数，或则限制创建Thread的数量，

给每个Thread设置对应的好听的名字，或则其他的很多很多事情，总之就是很爽，下面我们来展示一个简单的Thread

工厂模式来创建自己的Thread。

package com.bird.concursey;

import java.util.ArrayList;
import java.util.Date;
import java.util.Iterator;
import java.util.List;
import java.util.concurrent.ThreadFactory;

public class MyThreadFactory implements ThreadFactory {
	
	private int counter;
	private String name;
	private List<String> stats;
	
	public MyThreadFactory(String name) {
		counter = 0;
		this.name = name;
		stats = new ArrayList<String>();
	}

	@Override
	public Thread newThread(Runnable run) {
		Thread t = new Thread(run, name + "-Thread-" + counter);
		counter++;
		stats.add(String.format("Created thread %d with name %s on%s\n" ,t.getId() ,t.getName() ,new Date()));
		return t;
	}
	
	public String getStas() {
		StringBuffer buffer = new StringBuffer();
		Iterator<String> it = stats.iterator();
		while(it.hasNext()) {
			buffer.append(it.next());
			buffer.append("\n");
		}
		return buffer.toString();
	}
	
	public static void main(String[] args) {
		MyThreadFactory factory = new MyThreadFactory("MyThreadFactory");
		Task task = new Task();
		Thread thread = null;
		for(int i = 0; i < 10; i++) {
			thread = factory.newThread(task);
			thread.start();
		}
		System.out.printf("Factory stats:\n");
		System.out.printf("%s\n",factory.getStas());
		
		
	}

}
