利用Java写一个三个窗口随机买票的程序

以下是基于Java Swing编写的随机买票程序：

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

public class TicketPurchase extends JFrame implements ActionListener{
    
    private static final long serialVersionUID = 1L;
    private JLabel label1,label2,label3;
    private JButton button;
    private JTextField text1,text2,text3;
    private ArrayList<String> tickets = new ArrayList<String>();
    private String[] seatTypes = {"商务座","一等座","二等座","软卧","硬卧","硬座"};
    private String[] ticketPrices = {"200元","150元","100元","180元","120元","80元"};
    private Random random = new Random();
    
    public TicketPurchase(){
        setTitle("随机买票");
        setSize(400,200);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLocationRelativeTo(null);
        setLayout(new GridLayout(4,2));
        
        label1 = new JLabel("商务座：");
        label2 = new JLabel("一等座：");
        label3 = new JLabel("二等座：");
        button = new JButton("购买");
        text1 = new JTextField();
        text1.setEditable(false);
        text2 = new JTextField();
        text2.setEditable(false);
        text3 = new JTextField();
        text3.setEditable(false);
        
        add(label1);
        add(text1);
        add(label2);
        add(text2);
        add(label3);
        add(text3);
        add(button);
        
        button.addActionListener(this);
        
        setVisible(true);
    }
    
    public void actionPerformed(ActionEvent e){
        if(e.getSource() == button){
            tickets.clear();
            for(int i=0; i<6; i++){
                int randomNum = random.nextInt(10);
                String ticket = seatTypes[i] + " " + ticketPrices[i] + " " + randomNum + "张";
                tickets.add(ticket);
            }
            text1.setText(tickets.get(0));
            text2.setText(tickets.get(1));
            text3.setText(tickets.get(2));
        }
    }
    
    public static void main(String[] args){
        new TicketPurchase();
    }
}

程序界面包含三个文本框和一个按钮，点击按钮即可随机生成三种票的信息（票种、价格、数量），并将信息显示在对应的文本框中。
