如何使用多线程模拟公平抢票？

import java.util.concurrent.locks.ReentrantLock;

public class FairTicket搶票 {
    private static final int TOTAL_TICKETS = 10;
    private static final int TOTAL_USERS = 100;

    // 使用公平锁
    private static ReentrantLock fairLock = new ReentrantLock(true);

    public static void main(String[] args) {
        for (int i = 0; i < TOTAL_USERS; i++) {
            new Thread(() -> {
                fairLock.lock();
                try {
                    if (TOTAL_TICKETS > 0) {
                        System.out.println("用户" + Thread.currentThread().getName() + "抢到了第" + TOTAL_TICKETS + "张票");
                        TOTAL_TICKETS--;
                    } else {
                        System.out.println("用户" + Thread.currentThread().getName() + "没有抢到票");
                    }
                } finally {
                    fairLock.unlock();
                }
            }).start();
        }
    }
}
