模拟三个窗口卖票，统计每个窗口卖的票数，多线程怎么实现

场景：有100张火车票，长途2块钱，短途1块钱，现在有三个窗口线下卖票，统计每个窗口卖的票数，多线程怎么实现，注意三个窗口都可以卖短途和长途票，短途有30张，长途有70张。
程序如下: (注意，static 修饰的成员变量作为共享变量使用的)：

import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;

public class SellTicket implements Runnable {

    private static int totalTicketsLong = 70; //长途票
    private static int totalTicketsShort = 30; // 短途票数量
    private static Lock lock = new ReentrantLock(); //创建可重入锁
    private String windowName; //窗口名称
    private int soldTicketsLong = 0; //售出长途票数量
    private int soldTicketsShort = 0; // 售出短途票数量

    public SellTicket(String windowName){
        this.windowName = windowName;
    }

    @Override
    public void run() {

        while(totalTicketsLong > 0 || totalTicketsShort > 0){
            //模拟卖票过程
            int ticketType = (int) (Math.random() * 2); // 0 表示长途票， 1表示短途票
            if (ticketType == 0 || totalTicketsLong > 0) {
                sellTicketLong();
            } else {
                sellTicketShort();
            }
        }
        System.out.println(windowName + " 售票结束，售出长途票：" + soldTicketsLong + " 张，售出短途票：" + soldTicketsShort + " 张");
    }

    private void sellTicketShort() {
        lock.lock();
        try {
            if (totalTicketsShort > 0) {
                totalTicketsShort--;
                soldTicketsShort++;
                System.out.println(windowName + " 售出短途票，剩余短途票：" + totalTicketsShort + " 张");
            }
        } finally {
            lock.unlock();
        }
    }

    private void sellTicketLong() {
        lock.lock();
        try {
            if (totalTicketsLong > 0) {
                totalTicketsLong--;
                soldTicketsLong++;
                System.out.println(windowName + " 售出的长途票，剩余长途票：" + totalTicketsLong + " 张");
            }
        } finally {
            lock.unlock();
        }
    }

    public static void main(String[] args) {
        Thread window1 = new Thread(new SellTicket("窗口1"));
        Thread window2 = new Thread(new SellTicket("窗口2"));
        Thread window3 = new Thread(new SellTicket("窗口3"));

        window1.start();
        window2.start();
        window3.start();
    }
}

运行结果
