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();    
    }
}
