我想知道如何在Netbeans的已经打开的GUI中打开一个新的选项卡/窗口。如何打开新的选项卡或打开新窗口在按钮按下已经可见的GUI？
此外，我试图制作的游戏每个窗口都有1个问题，并且有4个答案按钮供您选择，如果您得到正确答案，您的分数将保存在可用于整个代码的变量中。

@MadProgrammer制成给予了很大的尖端，但如果它总是*一个问题，并且有4个答案，那么我倾向于在问题中只有一个'JLabel'，在一个按钮组中有4个'JRadioButton'对象用于答案。当用户选择一个答案并被告知正确/错误时，更改问题的文本（usinf'setText（）'）和可能的答案。这样做的优点是只需要一个面板即可处理多达数千个问题。 –
