    Default 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.
