如何在Swing中制作动态窗口？(How do I make dynamic windows in Swing?)

我有一个普遍的问题。 我想要一个包含一些按钮，单选按钮，文本字段等的窗口。 所以，用户可以做些事情（写文本，选择选项并按下按钮）。 由于用户活动窗口的结果应该改变它的结构/外观，某些元素应该消失并且出现一些元素。

我如何编程这种“更新”？ 我应该关闭一个旧窗口并打开一个新窗口，或者我可以修改窗口的内容而不关闭它？

I have a general question. I would like to have a window containing some buttons, radio buttons, text fields and so on. So, user can do something (write text, select options and press buttons). As the result of the user activity window should change it structure/appearance some element should disappear and some appear.

How do I program such "updates"? Should I close an old window and open a new one or I can modify content of window without closing it?

在添加组件之后，在容器上调用revalidate()将执行更新

After adding your components or such, calling revalidate() on your container will do the updates
