Thread: Class Driver help

Hello all, I require some help and I hope I am in the right forum.
I have a project I am attempting to do requiring me to build a window that accepts an input for a student ID number, and answers for a quiz to be taken. The window will have text fields for input of an answer to a question, which will be input into an array, compared with another array which holds the answer key, and then both of those shall be compared with a third which holds points for the correct answer. None of that is related to my problem now, but I thought it might help give an idea of what I am trying to envision the program to do. Right now I have two files, my main class file and my driver file (excuse me if I am naming them incorrectly). In my Class file, I have two void functions that are building the first panel for the user to input his/her student ID number. I have the panel fully built, I believe, besides the button's action listener to apply the information to the variable I set for it. In the driver file, I created a new object, and now I am trying to figure out a way to display it just to test my progress, but I am coming up short, and I cannot seem to find any resources to indicate what or how to do it. I apologize if this is an obvious mistake, but I don't see what I am doing wrong. I would appreciate any help in the matter, as well as any suggestions.
Thank you to anyone who can or will help.

Here is my class file.

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.text.*;
 
public class Quiz extends JFrame
{
    private int studentID;
    final private int SIZE = 8;
    private char[] quizAnswerkey = {'a', 'c', 'd', 'd', 'b', 'a', 'c', 'a'};
    private char[] quizAnswers = new char[SIZE];
    private int[] quizPoints = {10, 5, 10, 5, 5, 15, 20, 10};
    private JLabel messageLabel;
    private JTextField idText;
    private JButton storeButton;
    private JPanel panel;
 
 
    public void ID()
    {
        setTitle("Student ID info");
 
        setSize(310, 100);
 
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 
        buildIDpanel();
 
        add(panel);
 
        setVisible(true);
 
    }
    private void buildIDpanel()
    {
        messageLabel = new JLabel("Please enter your student ID number");
 
        idText = new JTextField(15);
 
        storeButton = new JButton("Input");
 
        panel = new JPanel();
 
        panel.add(messageLabel);
        panel.add(idText);
        panel.add(storeButton);
 
 
    }
 
 
 
}

and here is my driver file

public class QuizDriver 
 
{
    public static void main(String args[] )
    {
     Quiz quiz = new Quiz();
     quiz.
    }
 
}

I think that in programming approach you need first write the logic of your application, in separate class, and then think on how the user can interact with your application.

System.out.println(quiz.toString());
