I'm using JTabbedPane for my quiz program, not sure how to get my buttons to display the answers

Question

As it says, I'm not sure how to loop through the array so it would display the question in each pane, I got 8 panes and each of them should contain a question, I've managed to get it working for one (question 1 displays first entry in the array) but not the others.

Any suggestions?

int total = 0;
int counter = 0;
JPanel question1 = new JPanel();
JPanel question2 = new JPanel();
JPanel question3 = new JPanel();
JPanel question4 = new JPanel();
JPanel question5 = new JPanel();
JPanel question6 = new JPanel();
JPanel question7 = new JPanel();
JPanel question8 = new JPanel();
JTabbedPane quiz = new JTabbedPane();
JLabel lblQuestion1 = new JLabel();
JLabel lblQuestion2 = new JLabel();
JLabel lblQuestion3 = new JLabel();
JLabel lblQuestion4 = new JLabel();
JLabel lblQuestion5 = new JLabel();
JLabel lblQuestion6 = new JLabel();
JLabel lblQuestion7 = new JLabel();
JLabel lblQuestion8 = new JLabel();
JButton question1A = new JButton("Answer A");
JButton question1B = new JButton("Answer B");
JButton question1C = new JButton("Answer C");
JButton question2A = new JButton("Answer A");
JButton question2B = new JButton("Answer B");
JButton question2C = new JButton("Answer C");
JButton question3A = new JButton("Answer A");
JButton question3B = new JButton("Answer B");
JButton question3C = new JButton("Answer C");
Problem[] probList = new Problem[5];

public QuizEasy(){

    createLabel();

    questionsEasy();
    problems();
    nextQuestion();
    updateScreen();

    JButton finish = new JButton("Finish Quiz");
    question8.add(finish);

    //go forward one question if possible

Answer 1

To make things easier you could create a method called CreateTabs which would build every tab based on your list of problems(probList). See code below:

public void CreateTabs() {
    JPanel question = null;
    JLabel lbQuestion = null;
    JButton ansA = null;
    JButton ansB = null;
    JButton ansC = null;
    for (int i=0;i<probList.length;i++) {
        question = new JPanel();
        lbQuestion = new JLabel(probList[i].getQuestion());
        question.add(lbQuestion);
        ansA = new JButton(probList[i].getAnsA());
        ansB = new JButton(probList[i].getAnsB());
        ansC = new JButton(probList[i].getAnsC());
        question.add(ansA);
        question.add(ansB);
        question.add(ansC);
        quiz.addTab("Question " + (i+1), question); 
    }
}

In the QuizEasy constructor you would have something like:

public QuizEasy() {
    problems();
    CreateTabs();
    ...
}
