Creating a true/false java quiz.

Creating a true/false java quiz using BlueJ can be done through several steps. Below is an example Java program that implements a true or false quiz using a console-based approach. You can then integrate this logic into BlueJ for a graphical user interface (GUI) if needed.

import java.util.Scanner;

public class TrueFalseQuiz {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int score = 0;

    // Define the questions and answers in an array
    String[] questions = {"Java is a programming language. (True/False)", "BlueJ is an Integrated Development Environment (IDE). (True/False)"};
    boolean[] answers = {true, true};

    // Display the questions and get user input
    for (int i = 0; i < questions.length; i++) {
        System.out.println(questions[i]);
        String input = scanner.next();
        boolean userAnswer = input.equalsIgnoreCase("true");

        // Check the user's answer and update the score
        if (userAnswer == answers[i]) {
            System.out.println("Correct!");
            score++;
        } else {
            System.out.println("Incorrect!");
        }
    }

    // Display the final score
    System.out.println("Your score is: " + score + "/" + questions.length);
}

}

In this example, we have focused on creating a true/false java quiz, the program uses a Scanner to take user input and compares it with the correct answers. You can customize the questions and answers by modifying the questions and answers arrays.

To integrate this code into BlueJ for a GUI-based application, you can create a new class and use Java’s Swing or JavaFX libraries to build a graphical interface for the quiz. In a GUI-based application, you would replace the console-based input/output with graphical components such as buttons, labels, and text fields.

The code in text format –

// Define the questions and answers in an array String[] questions = {“Java is a programming language. (True/False)”, “BlueJ is an Integrated Development Environment (IDE). (True/False)”}; boolean[] answers = {true, true}; // Display the questions and get user input for (int i = 0; i < questions.length; i++) { System.out.println(questions[i]); String input = scanner.next(); boolean userAnswer = input.equalsIgnoreCase(“true”); // Check the user’s answer and update the score if (userAnswer == answers[i]) { System.out.println(“Correct!”); score++; } else { System.out.println(“Incorrect!”); } } // Display the final score System.out.println(“Your score is: ” + score + “/” + questions.length); }
