Android Studio Cumulative Project No. 4

Here’s the link to the project I’m dealing with:

Hello! I am working on the Android Studio Cumulative Project No. 4 and I am stuck on step 14. I created my .onAnswerSubmission method and the part I am stuck on is with my if statement. The error that shows when I execute my code (shown below) is:

error: non-static method isCorrect() cannot be referenced from a static context
      if (Question.isCorrect()) { 
1 error

My Code:

    // TODO #5 add getCurrentQuestion() here
    Question getCurrentQuestion() {
      return questions.get(currentQuestionIndex);
    // TODO #6 add onAnswerSubmission() here
    void onAnswerSubmission() {
      if (Question.isCorrect()) { 
        totalCorrect = totalCorrect + 1;

I thought what I was doing was right because I have to refer to the method in my file, specifically my isCorrect method. However, I keep receiving that error, so any help is much appreciated!!

Hi, I have been stuck on this same thing for a few days now. Did you ever figure it out?
