Cumulative project 2 - Getting "null when test printing data


I’m getting “null” returned when I test and print as per Step 9 of the Cumulative Project 2. The text of the questions is different to the project, but I’m baffled why the stated text isn’t returning? Any help appreciated. My code is below -

public class Question {
int correctAnswer;
int playerAnswer;
int imageId;
String questionText;
String answer0;
String answer1;
String answer2;
String answer3;

Question(int imageIdentifier, String questionString, String answerZero, String answerOne, String answerTwo, String answerThree, int correctAnswerIndex ){

imageIdentifier = imageId;
questionString = questionText;
answerZero = answer0;
answerOne = answer1;
answerTwo = answer2;
answerThree = answer3;
correctAnswerIndex = correctAnswer;
playerAnswer = -1;
} */

public class AndroidOS {
public AndroidOS() {
System.out.println(“AndroidOS Booting Up…”);


public void runQuizApp() {

    Question question1 = new Question(921238, "What line is he about to deliver?", "Twenty five, three tonnes of him", "Here's to smimmun' with bow-legged women", "Twelve hundred men went into the water", "Pretty good stuff huh chief!", 1);

Question question2 = new Question(107343, “What words are graffit’d on this?”, “Oh no, help!”, “Get me outa here!”, “Dinner!”, “Help shark!”, 3);

Question question3 = new Question(748294, “What’s the last instruction for Brody’s knot?”, “Comes out of the cave again”, “Little eel swims in the cave and done”, “Goes around the edge”, “and pull tight”, 0);

System.out.println("Question 1: " + question1.questionText);

public static void main(String[] args) {
    System.out.println("Starting: AndroidOS");
    AndroidOS androidOS = new AndroidOS();
