四则运算GUI版本

要求：用户界面新增支持 Windows GUI，同时保留原有命令行下所有功能。提示: 先测试驱动开发，然后重构代码，以GUI为目标修改"核心"函数，把与GUI/Console相关的部分提取出来
在原来实现四则运算的基础上通过java中的Swing组件实现了GUI版本
GUI的实现代码如下

    private ArrayList<String> RealAnswerList=new ArrayList<String>();  //存放真正的答案
    private String strAnswerAndResult[]=new String[2];
    private JLabel label_1;
    private JLabel lblNewLabel_3;
    private JButton submitButton;
    private JPanel panelNorth;
    private JPanel panelCenter;
    private JPanel panelSouth;
    private static int numOfQuestion; //问题的数量
    private String itemValue;   //难度级别
    private String recordWrong=" ";
    private String userName;
    private int countWrong=0;
    /**

     */
    public static void main(String[] args) {
