我正在尝试为我创建的游戏制作GUI，最初这个游戏是基于控制台的，但我正在努力提高我的技能并添加GUI。
我设法添加了一个按钮并添加了一个事件处理程序，所以当单击该按钮时，代码将会运行，但是，我想知道......
由于我的游戏以前是基于控制台的，我将把主要方法中的所有代码粘贴到GUI部分，然后如何将它用于打印出我用于GUI中的文本框的文本，然后我怎么能让它显示按钮（在这种情况下，攻击，防御或逃跑）。
我也想知道如何让代码等待用户单击其中一个按钮，然后单击该按钮时如何运行代码。
这是我在Main方法中的代码。这很冗长。

我建议首先阅读更多关于java swing的内容，甚至在youtube上观看并完成教程。你的问题：
问题：我也想知道如何让代码等待用户单击其中一个按钮，然后单击该按钮时如何运行代码。
答案：当您运行GUI代码时，它不会连续运行，它会等待并“监听”用户的输入。当您单击此按钮时，操作“侦听器”或您实现的任何侦听器将运行您要在按钮单击上运行的代码。
问题：由于我的游戏以前是基于控制台的，我将把主要方法中的所有代码粘贴到GUI部分，然后我将如何打印出我用于GUI中文本框的文本那么我怎么能让它显示按钮（在这种情况下，攻击，防御或逃跑）。
答案：GUI是一个巨大的领域，要弄清楚你希望窗口的外观，文本的打印位置和方式，请查看：
http://da2i.univ-lille1.fr/doc/tutorial-java/ui/features/components.html
对于这些按钮，你总是可以使用JButton，你仍然可以使用从键盘输入的1,2,3,4，就如何在这种情况下按下攻击，防御或逃跑。
关于windowsbuilder的另一件事是，在你的情况下，既然你已经把程序放在控制台上并且你想将它转换成GUI，那么如果你 don'它可能更容易，更快，更有价值使用windowbuilder 。手动完成。
