要有出发地目的地,顶票的张数,
添加单选按钮，让用户可选择单程或者往返
添加单行文本框，让用户可以输入购买张数
添加多行文本框，让用户可以输入意见
添加两个按钮, 分别为确认和退出

单选按钮：JRadioButton
复选框：JCheckBox
单行文本框：JTextField
多行文本框：JTextArea

下面是我写的一小部分,下面不知道该怎么完善,各位帮忙修改下..

import javax.swing.*;

class testGUI extends JFrame{
    JPanel jp1;
    JLabel start;
    JList startList;
    JButton jb1;
    JButton jb2;
   
    public testGUI(){
        super("订票演示");
        setVisible(true);
        setDefaultCloseOperation(EXIT_ON_CLOSE);   
        
        jp1 = new JPanel();
        
        //组件放入容器jp1
        start = new JLabel("出发地：");
        jp1.add(start);
        
        String[] str = {"深圳","北京","江西","湖南","重庆"};
        startList = new JList(str);
        jp1.add(startList);
        
        //容器加入到框架中
        getContentPane().add(jp1);
        pack();
    }
   
    public static void main(String[] args){
        testGUI tg = new testGUI();   
    }
}

花了20分钟写了下，现在swing程序写的都很乱，希望我写的可以帮你一下，感觉写的还算规范，公司基本都是这样要求的。

写得很复杂,很多知识点我都没有学到
有点看不清楚
不过你写得很规范!
值得我学习
谢谢你!

经鉴定 可以订负数张票 - -！

      
       SpinnerNumberModel spinnerNumberModel = new SpinnerNumberModel();
        spinnerNumberModel.setValue(1);
        spinnerNumberModel.setMinimum(1);
        
        JPanel typePnl = new JPanel();
        typePnl.setLayout(new GridBagLayout());
        ButtonGroup type = new ButtonGroup();
        singeRdo = new JRadioButton("单程");
        singeRdo.setSelected(true);
        doubleRdo = new JRadioButton("往返");
        countSpinner = new JSpinner(spinnerNumberModel);
        countLbl = new JLabel("张数：");

简单修改下就OK乐

不错，确实有这个问题。
