我在Swing应用程序上工作，显示来自主JFrame的不同＆＃34; sub＆＃34; JFrame。 我在一个名为FrameStratigraphie的特定＆＃34; sub＆＃34; JFrame上遇到了问题。
对于其他人＆＃34; sub＆＃34; JFrames，当我完成它们时，我只需处理它们并在以后需要时重新创建它们。但是这个，当我处理它并重新创建它时，动作侦听器会跳过X次，X就是我创建这个帧的次数。
以下是我设置动作监听器的方法：
bouton.addActionListener(lambda -> dispose());
我是lambda表达式的新手，所以问题可能来自这里。
我尝试通过setVisible（false）我的FrameStratigraphie来解决这个问题并尝试[removeAll + revalidate + repaint]但是如果我打开任何其他＆＃34; sub＆＃34; JFrame然后尝试重新创建它，那么框架只是灰色。就像没有添加任何组件一样。 （但是在removeAll（）之前我仍然可以看到正确的FrameStratigraphie 0.1秒。我想知道原因。
如果我执行JFrame.dispose（）
将我的框架设置为可见（false）后，为什么没有显示
这是我关于stackoverflow的第一篇文章，如果我在外观，拼写或相关性方面有任何错误，并且在我的代码中发表法语评论，我很抱歉......
提前感谢您提供与我的问题相关的任何信息，跟踪，建议，评论或答案。

答案 0 :(得分：2)
每次创建新的Stratagraphie时，都会调用：
bouton.addActionListener(lambda -> dispose());
Stratagraphie类中的所有变量都是静态的，这意味着每次创建新实例时都不会重新创建它们，因此您不断向该按钮添加新的ActionListener。
摆脱所有静态变量!!!
查看Swing教程中有关创建类使用的框架和变量的示例。来自How to Use Text Areas的TextDemo有一个简单的例子。
