JAVA 实现多线程发售火车票

public class demo05 {
    public static void main(String[] args) {
        TicketWindow tw = new TicketWindow();
        new Thread(tw,"窗口1").start();
        new Thread(tw,"窗口2").start();
        new Thread(tw,"窗口3").start();
        new Thread(tw,"窗口4").start();
    }
}
class TicketWindow2 implements Runnable{
    private int tickets = 100;
    public void run(){
        while (true){
            if (tickets>0){
                Thread th = Thread.currentThread();
                String name = th.getName();
                System.out.println(name+"正在发售"+tickets--+"张票");
            }
        }
    }
}
