java - 为猜谜游戏保存分数

Question

这是我目前在下面的代码。一切正常，但我不知道如何保持随机数的最低猜测分数。我如何跟踪高分（高分是猜测系统给出的随机数所需的最低猜测量）。我是一名初学者程序员，这是我第一次制作 gui，所以我为混乱道歉。

你看你在哪里：saveScore = clicked;？那是放置那行代码的坏地方。如果您设置saveScore为 equal clicked，然后在下一行代码中检查是否clicked小于或等于(<=) ，考虑到您设置为equalsaveScore的上一行代码，您认为会发生什么？saveScoreclicked

在其正下方saveScore = clicked;的语句代码块中作为第一行代码移动。只有在你知道确实小于之后才if使saveScore等于。clicked clickedsaveScrore
