用java实现下列功能： 多窗口卖票情况进度显示: (1)界面上显示两个以上的窗口卖票情况,每个窗口内容包括窗口名称(NJL_2_213_A本人姓名的首字母，班级号，对应学号后三位和窗口号码），该窗口分配的票数，已卖票数（建议用进度条加数字显示）； (2)所有窗口分配的票数总和等于自己学号的后三位数字，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或通过自动按钮一键完成（建议自动），窗口的每次卖票间隔不少于1秒。

以下是用 Java 实现上述功能的代码：

import javax.swing.*;
import java.awt.*;
import java.util.Random;

public class TicketSellingSystem extends JFrame {

    private static final int FRAME_WIDTH = 800;
    private static final int FRAME_HEIGHT = 600;
    private static final int NUM_WINDOWS = 3;
    private static final int MAX_TICKETS_PER_WINDOW = 50;

    private Window[] windows;
    private JButton manualBtn;
    private JButton autoBtn;
    private JProgressBar[] progressBars;

    public TicketSellingSystem() {
        setTitle("多窗口卖票情况进度显示");
        setSize(FRAME_WIDTH, FRAME_HEIGHT);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        // Create window objects
        windows = new Window[NUM_WINDOWS];
        int totalTicketCount = Integer.parseInt(getStudentId().substring(5));
        Random rand = new Random();
        for (int i = 0; i < NUM_WINDOWS; i++) {
            int windowNum = i + 1;
            int maxTickets = rand.nextInt(MAX_TICKETS_PER_WINDOW) + 1;
            windows[i] = new Window("NJL_2_213_A-W" + windowNum, maxTickets, totalTicketCount);
        }

        // Create progress bar components
        progressBars = new JProgressBar[NUM_WINDOWS];
        for (int i = 0; i < NUM_WINDOWS; i++) {
            progressBars[i] = new JProgressBar(0, windows[i].getMaxTickets());
            progressBars[i].setValue(windows[i].getSoldTickets());
            progressBars[i].setStringPainted(true);
        }

        // Create manual and auto buttons
        manualBtn = new JButton("手动卖票");
        autoBtn = new JButton("自动卖票");

        // Add components to frame
        JPanel panel = new JPanel();
        panel.setLayout(new GridLayout(NUM_WINDOWS + 2, 1));
        for (int i = 0; i < NUM_WINDOWS; i++) {
            panel.add(windows[i].getLabel());
            panel.add(progressBars[i]);
        }
        panel.add(manualBtn);
        panel.add(autoBtn);
        add(panel);

        // Add action listeners to buttons
        manualBtn.addActionListener(event -> sellTicketsManually());
        autoBtn.addActionListener(event -> sellTicketsAutomatically());
    }

    private void sellTicketsManually() {
        for (int i = 0; i < NUM_WINDOWS; i++) {
            int numSold = Integer.parseInt(JOptionPane.showInputDialog(this,
                    "请输入窗口 " + (i + 1) + " 卖出的票数："));
            windows[i].sellTickets(numSold);
            progressBars[i].setValue(windows[i].getSoldTickets());
        }
    }

    private void sellTicketsAutomatically() {
        for (int i = 0; i < NUM_WINDOWS; i++) {
            int numSold = new Random().nextInt(windows[i].getMaxTickets() - windows[i].getSoldTickets() + 1);
            windows[i].sellTickets(numSold);
            progressBars[i].setValue(windows[i].getSoldTickets());
        }
    }

    private String getStudentId() {
        return "201912345678";
    }

    public static void main(String[] args) {
        TicketSellingSystem system = new TicketSellingSystem();
        system.setVisible(true);
    }

    private class Window {

        private String name;
        private int maxTickets;
        private int soldTickets;

        public Window(String name, int maxTickets, int totalTicketCount) {
            this.name = name;
            this.maxTickets = maxTickets;
            this.soldTickets = 0;
            if (maxTickets > totalTicketCount) {
                this.maxTickets = totalTicketCount;
            }
        }

        public String getName() {
            return name;
        }

        public int getMaxTickets() {
            return maxTickets;
        }

        public int getSoldTickets() {
            return soldTickets;
        }

        public JLabel getLabel() {
            return new JLabel(name + "（已售 " + soldTickets + " 张，共 " + maxTickets + " 张）");
        }

        public void sellTickets(int numSold) {
            if (soldTickets + numSold <= maxTickets) {
                soldTickets += numSold;
            }
        }
    }
}

代码中创建了一个 `TicketSellingSystem` 类，用于显示多个窗口的卖票情况和实现手动或自动卖票。`Window` 类用于表示每个窗口的状态。卖票数量是通过随机数生成的，手动卖票时通过对话框输入。进度条和数字显示用 `JProgressBar` 组件实现。
