Thinking in Java學習筆記，簡單包裝Thread，實現快速實現線程

package com.test.concurrent;

public class SimpleThread extends Thread {
	private static int counter=0;
	private int countDown=5;
	public SimpleThread(){
		super(String.valueOf(counter++));
		run();
	}
	public void run(){
		while(true){
			if(countDown--==0){
				return;
			}
			System.out.println("#"+getName()+"  "+this+"   countDown:"+countDown);
		}
	}
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		for(int i=0;i<5;i++){
			new SimpleThread();
		}
	}

}
