Putting the values of an array into a combobox

Question

Hey I'm looking for some advice on an error I'm getting
First heres the program:
import java.awt.*;
import javax.swing.*;
import java.util.*;
import java.awt.event.*;
public class Quizgame implements EventListener {
     JPanel mainPanel;
     JFrame theFrame;
     public static void main(String[] args) { Quizgame b = new Quizgame(); b.buildGUI(); }
     public void buildGUI() {
          Quizbook Q = new Quizbook("C:\\Users\\Boab\\Desktop\\JavaRe-sit\\FileInput.txt");
          String question = Q.getContent(0);
          String Ans1= Q.getContent(1);
          String Ans2= Q.getContent(2);
          String Ans3= Q.getContent(3);
          String Ans4= Q.getContent(4);
          theFrame=new JFrame("QuizGame");
          BorderLayout layout = new BorderLayout();
          JPanel background = new JPanel(layout);
          background.setBorder(BorderFactory.createEmptyBorder(10,10,10,10));
          Box buttonBox = new Box (BoxLayout.Y_AXIS);
          JButton start = new JButton("Submit");
          start.addActionListener(new MyStartListener());
          buttonBox.add(start);
          JComboBox Answer = new JComboBox(Q);
          start.addActionListener(new MyStartListener());
          buttonBox.add(Answer);
          Box QuestionBox = new Box(BoxLayout.X_AXIS);
          Box nameBox = new Box(BoxLayout.Y_AXIS);
          nameBox.add (new Label(Ans1));
          nameBox.add (new Label(Ans2));
          nameBox.add (new Label(Ans3));
          nameBox.add (new Label(Ans4));
          QuestionBox.add(new Label(question));
          background.add(BorderLayout.EAST, buttonBox);
          background.add(BorderLayout.WEST, nameBox);
          background.add(BorderLayout.NORTH, QuestionBox);
          theFrame.getContentPane().add(background);
          GridLayout grid = new GridLayout(16,16);
          grid.setVgap(1); grid.setHgap(2);
          mainPanel = new JPanel(grid);
          background.add(BorderLayout.CENTER, mainPanel);
          theFrame.setBounds(150,150,1,1); theFrame.pack(); theFrame.setVisible(true);
     public class MyStartListener implements ActionListener {
     public void actionPerformed(ActionEvent a) {
               //where you put whats to happen
     public class comboListener implements ActionListener {
     public void actionPerformed(ActionEvent a) {
               //where you put whats to happen
     There is another file which creates an array of strings with the instance Q in this class ^
I'm trying to fill the combobox with the values of the array but I can't get it too work. With the code as it is now I get:
C:\Users\Boab\Desktop\Seperate Java files\NewQuiz\Quizgame\Quizgame.java:41: cannot find symbol
symbol : constructor JComboBox(Quizbook)
location: class javax.swing.JComboBox
          JComboBox Answer = new JComboBox(Q);
^
1 error
I don't really understand why it doesn't work, When I look up the error online its about the class but it works fine without the Combobox line. Any ideas why it won't put the array into the combobox?
Also my next step is to put only certain values into the combobox i.e values 2-4 in the array, Is there any smart piece of code to do this or do I need to put a loop in with an addcontent and hardcode it?
Thanks for any help

Answer 1

Yeah sorry, Quizbook is a class with a method to read out the array the method is:
     public String getContent(int element)
          //access arraylist and return
          return (String)Quizbook.get(element);
     so I tried what you said and put :
JComboBox Answer = new JComboBox(Q.getContent(5));
Because the Answer is at that location in the array but it gave me the same error message:
C:\Users\Boab\Desktop\Seperate Java files\NewQuiz\Quizgame\Quizgame.java:41: cannot find symbol
symbol : constructor JComboBox(java.lang.String)
location: class javax.swing.JComboBox
          JComboBox Answer = new JComboBox(Q.getContent(3));
^
1 error
Process completed.
So I would of thought that meant use the getContent method from Q object with element bieng 3?
