这段代码是一个简单的模拟售票程序，它创建了一个窗口，包含两个进度条和一个“开始”按钮。总共有 108 张票，两个窗口分别出售随机数量的票，直到所有票都售出为止。

要显示已售票的份数，可以在程序中添加一个标签或文本框，每次销售后更新它的文本。例如，在 `sellTickets()` 方法中，可以添加以下代码：

if (windowNum == 1) {
    if (ticketSold1 + ticketSold <= totalTickets) {
        ticketSold1 += ticketSold;
        progressBar1.setValue(ticketSold1);
        label1.setText("LYH_1_108_1: " + ticketSold1 + " sold");
    }
} else {
    if (ticketSold2 + ticketSold <= totalTickets) {
        ticketSold2 += ticketSold;
        progressBar2.setValue(ticketSold2);
        label2.setText("LYH_1_108_2: " + ticketSold2 + " sold");
    }
}

这将在售票时更新标签的文本，以显示已售票的份数。
