java - 问卷 GUI(我的第一个 GUI)跳过了我的问题？

Question

我正在尝试创建一个简单的 GUI，它会询问用户一系列问题，然后存储他们的回答以供稍后分配。我已经确定我的错误出在我的方法中，该方法基本上执行了简单的 7 个问题。我已将 7 个问题添加到 ArrayList 中，并为我的答案创建了一个空的 ArrayList，但是当我运行该方法时，它唯一显示的是最后一个问题的文本。

显然是一个 Java 菜鸟，但 100% 是一个 GUI/swing/AWT 菜鸟，并且真的感觉我不知道自己在做什么，所以任何人都愿意付出任何时间或精力来尝试教育我我们将不胜感激，并提前感谢您!!

如果您想循环浏览问题，则无法一次加载所有问题。

当您单击输入按钮时，类似这样的内容应该加载下一个问题。

private int questionIndex; // store which question youre on 

private void calcPersonnelRisk() {
    yesButton.setVisible(false);
    noButton.setVisible(false);
    message.setFont(new Font("Tahoma", Font.BOLD, 14));
    // load the first question 
    message.setText(questions.get(questionIndex++));

    enterButton.addActionListener(new ActionListener(){
        public void actionPerformed(ActionEvent e){
            int r= Integer.parseInt(textField.getText().trim());
            responses.add(r);

            // load the next question 
            if (questionIndex < questions.size()) {
                message.setText(questions.get(questionIndex++));
            } else {
                message.setText("Done");
            }
        }});
    }
}
