航班信息查询与检索(java)

大二上时用C语言写过一个关于航班信息查询与检索的课程设计,当时是自己抄代码,然后再让学长帮改的,前天晚上在“抄”代码时,突然想用java把那个课设题再写一次,于是昨天晚上就开始了,当然还是先在网上找了不少“成品”做参考,半借鉴,半修改,马马虎虎写了一个功能比较少的版本,以后再写更高版本的。
       这个小程序的代码分为四个模块:主框架(MainWindow),关于飞机航班号、起飞(目的)城市与起飞时间(Plane),对航班信息的添加查询等操作(FlightInfoOperation),以及对文件的处理(IOOperation)。
      主窗口图:
      
    添加窗口图:
  
  查询窗口图:
  (其中可以通过航班号、起飞城市任意一个查询或两者查询)
  
 
下面给出这个代码的部分代码:
FlightInfoOperation里的
  

[java]
public FlightInfoOperation() { 
 
    mainFrame = new Frame("航班信息查询与检索"); 
    mainFrame.addWindowListener(new WindowAdapter() { 
        public void windowClosing(WindowEvent e) { 
            System.exit(0);

    mainFrame.setLocation((screenSize.width - frameSize.width) / 2, 
            (screenSize.height - frameSize.height) / 2); 
 
    buttonPanel = new Panel();
