大家好,我有这段代码,并且我一直在努力一段时间。这是一种游戏,当单击“开始”按钮时,一堆按钮会弹出到屏幕上,并且高亮显示一个按钮,如果玩家单击突出显示的按钮,则该玩家将获得得分,但如果玩家未单击正确的按钮,则该玩家将失去得分。游戏运行正常,但是当我尝试使主菜单出现问题时。当我单击开始按钮时,它将打开应该在其中进行游戏的窗口(它具有正确的窗口名称,所以我知道它的工作原理),但是没有任何按钮。有人可以帮忙,因为我一直在这个问题上停留了大约一周。
谢谢

最佳答案
代替弹出一个新窗口(请参见The Use of Multiple JFrames, Good/Bad Practice?),更好的做法是使用CardLayout
在视图之间交换。主菜单可以是面板视图,游戏可以是面板视图。
