我一直在研究应该是一个相对简单的游戏，Mormon Sim。目标是在挨家挨户时进行成功的对话。这很简单，只需单击一个按钮，它就会根据调用的按钮和方法更改JLabel的文本。例如，使用Knock按钮将激活方法knockResponse，它将计算是否有人会来到门口。根据计算结果，有人会回答您的门，否则您将被拒之门外。问题是，经过几次点击后，通常一旦玩家通过敲击检查，JLabel就会开始回复到其他文本，并在几个不同的东西之间来回，有时完全无视他们的挥动计时器。我真的不知道这里发生了什么，我真的找不到这种情况会发生的原因。整整一周的谷歌搜索没有产生类似的问题或解决方案。 TL; DR Java已经自我意识

感谢您的帮助，我很难提问。

默认情况下为Timer starts out repeating。所以，你的计时器每一秒都在燃烧，永远。
你应该致电setRepeats(false)：
void doLater(ActionListener action, int delay) {
Timer timer = new Timer(delay, action);
timer.setRepeats(false);
timer.start();
}
