I made a quiz about classes using a class. The facts are from chatgpt.

import java.util.ArrayList;
import java.util.Scanner;

public class JavaClass {
    ArrayList<String> chatgptFacts = new ArrayList<String>();
    ArrayList<Boolean> chatgptAnswers = new ArrayList<Boolean>();

    public JavaClass() {
        chatgptFacts.add("A class is a blueprint for creating objects.");
        chatgptAnswers.add(true);
        chatgptFacts.add("An object is an instance of a class.");
        chatgptAnswers.add(true);
        chatgptFacts.add("A constructor is a special method that is called when an object is created.");
        chatgptAnswers.add(true);
        chatgptFacts.add("A method is a block of code that performs a specific task.");
        chatgptAnswers.add(true);
        chatgptFacts.add("Inheritance is the process by which one class acquires the properties of another class.");
        chatgptAnswers.add(true);
        chatgptFacts.add("Java is a procedural programming language.");
        chatgptAnswers.add(false);
        chatgptFacts.add("Encapsulation in Java is a mechanism of wrapping the data and code together as a single unit.");
        chatgptAnswers.add(true);
    }

    public void quiz() {
        Scanner scanner = new Scanner(System.in);
        int score = 0;
        
        for (int i = 0; i < chatgptFacts.size(); i++) {
            System.out.println(chatgptFacts.get(i));
            System.out.print("(Type True or False)");
            String answer = scanner.nextLine();
            
            if (answer.equalsIgnoreCase(Boolean.toString(chatgptAnswers.get(i)))) {
                score++;
            }
        }
        
        System.out.println("Your score is " + score + " out of " + chatgptFacts.size());
    }
}

JavaClass jc = new JavaClass();
jc.quiz();
