Thanks a lot for your help. I really appreciate it. I tried to arrange the code in the GQ as you have told me, but still there's something wrong, because its not stopping and displaying the result. Can you pls help me figure out the problem? Thanks a lot.

This is the code in the GQ class:

Code:

import java.awt.*;
import java.awt.event.*;
import java.util.*;
import java.io.*;
import javax.swing.*;
import java.util.Calendar;
 
public class GQ extends JFrame implements ActionListener {
    private static final int FRAME_WIDTH = 140;
    private static final int FRAME_HEIGHT = 160;
    private static final int FRAME_X_ORIGIN = 70;
    private static final int FRAME_Y_ORIGIN = 50;
    AnswerStore answerStore = new AnswerStore();

 
    
    public static void main (String[] args) {
        
        
       

        JOptionPane.showMessageDialog(null, "This is a Geography Quiz");
        JOptionPane.showMessageDialog(null, "Good Luck");
 
        
 
            GQ frame = new GQ();
            frame.setVisible(true);
       
    }
 
    public GQ() {
        Container contentPane;
        JButton button1, button2, button3, button4, button5;
 
        setSize (FRAME_WIDTH, FRAME_HEIGHT);
        setTitle("Geography Quiz");
        setLocation(FRAME_X_ORIGIN, FRAME_Y_ORIGIN);
 
        contentPane = getContentPane();
        contentPane.setBackground(Color.pink);
        contentPane.setLayout(new FlowLayout());
 
        button1 = new JButton("Plate Tectonics");
        button2 = new JButton("Rivers");
        button3 = new JButton("Rocks");
        button4 = new JButton("Quit");
 
        contentPane.add(button1);
        contentPane.add(button2);
        contentPane.add(button3);
        contentPane.add(button4);
    
        button1.addActionListener(this);
        button1.setActionCommand("b1");
        button2.addActionListener(this);
        button2.setActionCommand("b2");

        button4.setActionCommand("b4");
        setDefaultCloseOperation(EXIT_ON_CLOSE);
    }
  
     public void actionPerformed(ActionEvent e) {
        String ac = e.getActionCommand();
        String[] questions = null;
        String[] answers = null;
        if (ac.equals("b1")) {
            questions = readFile("plate_tectonics.txt");

        } else if(ac.equals("b2")) {

         //it displays the message "time is over" the program isn't stopping and displaying the results. 
        }
