我的 GUI 不适用于我的井字游戏……我想知道我做错了什么/出了什么问题，为什么这不能正常工作？游戏应该有九个盒子和井字游戏，然后能够点击盒子来获得 X 和 O，直到有人获胜。

这几乎是我现在的问题。如问题中所述，GUI 不起作用。它会询问玩家姓名以及您想成为哪个字母，X 或 O。就是这样。我想知道为什么带有九个框的 GUI 不显示。

这是我的代码：

import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;

您有两个 JFrame、类本身和 window 变量。一个 JFrame 窗口获取所有按钮，而另一个则显示。我建议您不要让您的类扩展 JFrame，而是显示窗口 JFrame。
