Sorry, but can you explain more specifically pls?
By the way here is the full code, I'm trying to apply data file into a quiz program and collect answers from combobox selection, which is adding them into an array:
public void go(){          
          fc = new JFileChooser();           
          //Presentation Part
          //JTable
          String[] columnNames={"Question","Answer","Points"};
          Object[][] data={};
          dtm = new MyTableModel(data, columnNames);
          table=new JTable(dtm);
          table.setPreferredScrollableViewportSize(new Dimension(500,570));
          JScrollPane scrollPane= new JScrollPane(table);
          //image Icon
          iIcon = new ImageIcon("icon1.jpg");
          //Setup Two Buttons for main Panel
          button = new JButton("Load Questions");
          button2 = new JButton("Calculate Score");
          button.addActionListener(new ButtonListener());
        button2.addActionListener(new ButtonListener());
          //Set panels to frame
          JPanel mainPanel = new JPanel();
          mainPanel.add(button,"South");
          mainPanel.add(button2);
          mainPanel.add(scrollPane);
          //Set frame
          frame = new JFrame("IOExample");
          frame.getContentPane().add(mainPanel);
          frame.setSize(750, 720);
          frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
          frame.setVisible(true);
     public static void main(String[] args) {               
               Homework3 example = new Homework3();
               example.go();
     public class ButtonListener implements ActionListener{
          public void actionPerformed(ActionEvent e) {
                 String command = e.getActionCommand();
                 //read selected answers                 
                if (command.equals("Calculate Score")) {
                     for (int j=0;j<i;j++){                         
                          Object index = comboBox[j].getSelectedItem();
                         checkList[j]=(String) index;
                          System.out.println("test "+(j+1)+" "+checkList[j]);
                        checkList[0]= (String) comboBox[0].getSelectedItem();
                         System.out.println(Thread.currentThread().getContextClassLoader().getResource(""));
                // read data and apply to interface
                 if (command.equals("Load Questions")) {
                      if(e.getSource()==button){
                           int returnVal=fc.showOpenDialog(frame);
                           if (returnVal==JFileChooser.APPROVE_OPTION){
                                File file=fc.getSelectedFile();
                                //open file and split in to lines
                                try {
                                     String thisLine;
                                     ArrayList<String> arrayList=new ArrayList<String>();
                                    FileReader fr= new FileReader(file);
                                    BufferedReader br = new BufferedReader(fr);
                                    i = 0;
                                    while ((thisLine = br.readLine()) != null) { // while loop begins here
                                             // split row and add it to table
                                             arrayList.add(thisLine);
                                              String row [] = null;
                                              row = thisLine.split(";");

                                        temp = row[1].split("/");
                                        //add 3 options to ComboBox
                                        comboBox[i]=new JComboBox();                              
                                             comboBox[i].addItem(temp[0]);
                                             comboBox[i].addItem(temp[1]);
                                             comboBox[i].addItem(temp[2]);
                                             comboBox[i].setSelectedItem(temp[0]);
                                             answer.setCellEditor(new DefaultCellEditor(comboBox[i]));
                                             //comboBox[i].addActionListener(new ComboBoxListener());
                                        i++;
                                             System.out.println("Q"+i+" Correct Answer: "+row[3]);
                              br.close();
                              catch (IOException e1) {
                              System.err.println("Error: " + e1);
                    }else {System.out.println("Sorry! no file");
