已经完成了大部分代码。 如何创建JTable并成功实现以下指示？

Question

----------

如何在我的代码中实现以下说明？

•   **Create a New TablePanel Class**
•   the Table Panel class should extend the JPanel class
•   On this panel you will create your new JTable table.

•   **Update the MainFrame class**
•   Initialize the Table Panel class
•   add it to the frame
•   update the frame layout with a 2 row, 1 column grid layout.

•   **Update the Model class**
•   write a new getTableDate()function that returns a DefaultTableModel class from
•   javax.swing.table.DefaultTableModel;
•   Set the Table Model headers in a String [];
•   Convert the student data (sts variable) into Object[] rowdata for the table

•   **Update the View**
•   write a tableSetup function that takes (TableModel dataModel) as a parmeter
•   call the mainframe’s table panel class and set the table’s model to the passed in dataModel.

•   **Update the Controller**
•   Initialize the JTable by calling the tableSetup() function you wrote for thr View, and passing in the dataModel return from the model.getDataModel() function. At this point you should be able to see the data loaded into the table.
•   Update the actionListener to call the tableSetup() function, this will update the table display when a button is clicked in the user interface.

Controller.java

    public class Controller implements MouseListener{
      public JButton dataButton;

      Model model;

      View view;

      public Controller(Model model, View view){ 
      this.model = model;

        this.view = view;

        for (int i = 0; i < 15; i++){

            view.mf.ip.displayData(model.findStudent(i).getInfo());

            view.mf.ip.addMouseListener(this); }}


    @Override

    public void mouseClicked(MouseEvent me){}

    @Override

    public void mousePressed(MouseEvent me){}

    @Override

    public void mouseReleased(MouseEvent me){}

    @Override

    public void mouseEntered(MouseEvent me){}

    @Override

    public void mouseExited(MouseEvent me){}

    private void add(JButton dataButton){}

    private int getSource(int i){return 0;
    }

模型

        Student st1 = new Student("Emily", "Smith", 20, addr1);

        MailAddress addr2 = new MailAddress("200 W College Avenue", "State College", "PA", 16801);

        Student st2 = new Student("Mary", "Doe", 20, addr2);

        MailAddress addr3 = new MailAddress("300 W College Avenue", "State College", "PA", 16801);

        Student st3 = new Student("John", "Doe", 20, addr3);

        //add them to the array of students

        sts.add(st1);

        sts.add(st2);

        sts.add(st3);}

    public Student findStudent(int studentNum)

    {Student foundStudent;

        if (getSts().size() > studentNum){

            foundStudent = getSts().get(studentNum);}

        else{return null;}

        return foundStudent;}

    public ArrayList<Student> getSts(){
        return sts;}

      public void setSts(ArrayList<Student> sts)

      { this.sts = sts; }}

        setDefaultCloseOperation(EXIT_ON_CLOSE);

        add(ip, "Center");

        setSize(720, 280);

        setVisible(true); }

        public InitialPanel getIp()
