一个Java线程小例子（仿火车票售卖）

public class MyThread extends Thread{
private static int ticket=100;
public void run(){
for(int i=0;i<50;i++)
if(ticket>0)
System.out.println(Thread.currentThread().getName()+"正在卖第"+(ticket--)+"张票");
}

//main函数是一个主线程
public static void main(String[] args) {
MyThread mt=new MyThread();
Thread m1=new Thread(mt,"window1");
Thread m2=new Thread(mt,"window2");
Thread m3=new Thread(mt,"window3");
m1.start();
m2.start();
m3.start();
}
}
