Results.java 类中的 showResults() 方法的输出无法正常工作。琐事游戏循环遍历所有 10 个问题并显示供用户选择答案。第 10 题之后，会显示一个结果页面，其中包含正确和错误答案的结果。正确的问题将显示为绿色，不正确的问题将显示为红色。问题的颜色没有以正确的颜色显示。此外，变量“correctAnswers”和“wrongAnswers”不会在 QuestionView 类中递增。这可以从 Results.java 中的 showResults() 的输出中看出。
我已经在很多地方进行了调试，但似乎无法找到我搞砸的地方。
对此问题的帮助以及代码结构建议表示赞赏！先感谢您！
