用Java代码完成以下任务 多窗口卖票情况进度显示： (1）界面上显示两个窗口卖票情况，第一个窗口分配的票数是107，窗口名称是LK _2_215_1。第二个窗口分配的票数是108，窗口名称是LK _2_215_2. 每个窗口内容包括 1.窗口名称，2.该窗口分配的票数，3.已卖票数（用进度条加数字显示） (2）每个窗口每次卖出的票数由随机数指定， (3）启动卖票行为，由每次通过按键手工启动

以下是用Java代码实现多窗口卖票情况进度显示的示例代码：

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.Random;

public class TicketSellingSystem extends JFrame implements ActionListener {
    private JLabel window1Name;
    private JLabel window2Name;
    private JLabel window1TicketCount;
    private JLabel window2TicketCount;
    private JLabel window1SoldCount;
    private JLabel window2SoldCount;
    private JProgressBar window1ProgressBar;
    private JProgressBar window2ProgressBar;
    private JButton sellButton;
    private int window1TicketTotal = 107;
    private int window2TicketTotal = 108;
    private int window1TicketSold = 0;
    private int window2TicketSold = 0;
    private Random random = new Random();

    public TicketSellingSystem() {
        setTitle("票务销售系统");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(400, 300);
        setLocationRelativeTo(null);
        setLayout(new GridLayout(3, 2));

        window1Name = new JLabel("LK_2_215_1");
        add(window1Name);
        window2Name = new JLabel("LK_2_215_2");
        add(window2Name);

        window1TicketCount = new JLabel("票数：" + window1TicketTotal);
        add(window1TicketCount);
        window2TicketCount = new JLabel("票数：" + window2TicketTotal);
        add(window2TicketCount);

        window1ProgressBar = new JProgressBar(0, window1TicketTotal);
        window1ProgressBar.setStringPainted(true);
        add(window1ProgressBar);
        window2ProgressBar = new JProgressBar(0, window2TicketTotal);
        window2ProgressBar.setStringPainted(true);
        add(window2ProgressBar);

        window1SoldCount = new JLabel("已售：" + window1TicketSold);
        add(window1SoldCount);
        window2SoldCount = new JLabel("已售：" + window2TicketSold);
        add(window2SoldCount);

        sellButton = new JButton("卖票");
        sellButton.addActionListener(this);
        add(sellButton);

        setVisible(true);
    }

    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == sellButton) {
            if (window1TicketSold < window1TicketTotal && window2TicketSold < window2TicketTotal) {
                int window1SellNum = random.nextInt(5) + 1; // 随机卖出1-5张票
                int window2SellNum = random.nextInt(5) + 1;
                if (window1TicketSold + window1SellNum > window1TicketTotal) {
                    window1SellNum = window1TicketTotal - window1TicketSold;
                }
                if (window2TicketSold + window2SellNum > window2TicketTotal) {
                    window2SellNum = window2TicketTotal - window2TicketSold;
                }
                window1TicketSold += window1SellNum;
                window2TicketSold += window2SellNum;

                window1TicketCount.setText("票数：" + window1TicketTotal);
                window2TicketCount.setText("票数：" + window2TicketTotal);
                window1SoldCount.setText("已售：" + window1TicketSold);
                window2SoldCount.setText("已售：" + window2TicketSold);
                window1ProgressBar.setValue(window1TicketSold);
                window2ProgressBar.setValue(window2TicketSold);
            } else {
                JOptionPane.showMessageDialog(null, "票已售完！");
            }
        }
    }

    public static void main(String[] args) {
        new TicketSellingSystem();
    }
}

运行该程序可以看到一个包含两个窗口卖票情况的界面，每次点击“卖票”按钮会随机卖出1-5张票，并更新窗口显示的已卖票数和进度条。当票已售完时会弹出提示框。

注意：该程序只是一个示例，实际应用中还需要考虑线程安全、用户界面交互等方面的问题。
