Based on your code, it seems that you are not updating the value of the currentIndex variable after iterating through your QuestionList array. This is why the same question is being displayed even if you click the Next button.

To fix this issue, you can update the value of the currentIndex variable every time the Next button is clicked. Here's how you can modify your nextButton.addActionListener() method:

Java: 
nextButton.addActionListener((ActionEvent h) -> {
    if (currentIndex < QuestionList.size() - 1) {
        currentIndex++; // Increment the current index
        
        // Get the next question and update the JTextArea
        String nextQuestion = QuestionList.get(currentIndex);
        playTextQues.setText(nextQuestion);
    } else {
        // No more questions, display a message or perform any other desired action
        JOptionPane.showMessageDialog(null, "No more questions.");
    }
});

In this updated code, we first check if there are still questions left to display by comparing the value of currentIndex with the size of the QuestionList array. If there are still questions left, we increment the value of currentIndex and get the next question from the QuestionList array using QuestionList.get(currentIndex). Finally, we update the text of the playTextQues JTextArea with the next question.

If there are no more questions left to display, we can display a message to the user using a JOptionPane. You can modify this as per your requirement.
