我只想从一帧转到另一帧。 我列出了一个列表，您可以从中进行选择，然后当您单击按钮确认时它应该显示一个不同的窗口。遗憾的是它没有。
这是我的第一个 Jframe 中的类，所以我的第一个带有确认按钮的窗口:

我真的卡在这里了，请帮忙!谢谢你的时间:)对不起我的英语
最佳答案
您的代码似乎过于宽泛且没有必要进行演示，而所需的最少代码却非常小。
即便如此，我也会针对您的问题写一个简短的答案。考虑到您必须退出 jframe1 并移动到 jframe2，在确认按钮的操作执行事件中，只需添加以下行:-
public static void jButton1 ActionPerformed......{
jFrame1.dispose();
jFrame2.setVisible(true);
}
关于java - 单击按钮时如何显示新的 Jframe，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/27668482/
