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
public class CalMachineSwingBuild extends JFrame {
private JPanel contentPane;
private JComboBox comboBox;
private JLabel lblNewLabel;
private JTextField textField;
private JLabel lblNewLabel_1;
private ArrayList<String> questionList=new ArrayList<String>();
private ArrayList<JTextField> answersByUser = new ArrayList<JTextField>(); //存放用户填写的答案的文本域
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;
/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
CalMachineSwingBuild frame = new CalMachineSwingBuild();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/**
* Create the frame.
*/
public CalMachineSwingBuild() {
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(100, 100, 800, 600);
contentPane = new JPanel();
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
setContentPane(contentPane);
contentPane.setLayout(new BorderLayout(0, 0));
panelNorth=new JPanel();
JLabel label = new JLabel("难度值");
label.setBounds(10, 10, 42, 15);
panelNorth.add(label);
//contentPane.add(label);

comboBox.addItem("简单");
comboBox.addItem("普通");
comboBox.addItem("复杂");
comboBox.setBounds(62, 7, 50, 100);
comboBox.setEditable(false);
comboBox.setSize(60, 20);
panelNorth.add(comboBox);
// contentPane.add(comboBox);
lblNewLabel = new JLabel("题目数量");
lblNewLabel.setBounds(144, 10, 62, 15);

// contentPane.add(lblNewLabel);

textField.setBounds(216, 7, 46, 21);
// contentPane.add(textField);
textField.setColumns(10);
panelNorth.add(textField);

btnNewButton.setBounds(272, 6, 93, 23);
/* labelForSpec=new JLabel();
