我的GUI不是'；对于我的基于文本的冒险游戏，代码不会运行，但我所做的选择按钮不会运行；不行。为什么？Java Swing

我正在尝试用GUI制作一个基于文本的冒险游戏，一切都进行得很顺利，直到我遇到了一个问题，我的开始按钮可以工作，但我的选择按钮不能工作。我正在关注YouTube教程（）并在10:00左右陷入困境，有人能帮我吗？这是我的密码：

我几乎可以肯定，我的问题在我的故事和游戏课程中的某个地方，但为了以防万一，我把其余的都包括进去了。如果有帮助的话，我正在使用Eclipse

为什么要多次将choice1.setActionListner设置为cHandler？“我正在关注YouTube教程”-就我个人而言，我会避免它-它似乎没有给你提供很多好的想法-天哪，你解决了我的问题。我没有检查就复制并粘贴了它。谢谢
