问题描述
我正在尝试编写一个简单的子手游戏代码，除了以下两点外，一切都将进行:1)消息文本未显示
2)重启后，按钮将不会被禁用！我尝试使用切换按钮，但没有任何改变.

推荐答案
编辑了代码.
首先是2个小要点:
-不要以大写字母开头变量名称！您的按钮甚至都没有名称，只是"A"，"B"-更改名称！大写字母用于表示班级名称.
-提取所有操作，并在该GUI类之外设置控制器类.将控制器设为Actionlistener-您将获得更简洁的代码，具有更多的结构.
对您的问题:
1.哪一个messege文本?我找不到你的意思.您的函数entLetter(char en)中的String msg不是可显示的项目.
2.您需要使用this.redraw()重新加载GUI-在这种情况下，您无需将按钮设置为"false".
问候

edited the code.
first of all 2 small points:
- do not start variable names with capital letters! Your buttons don''t even have a name it''s just "A", "B" - change that! Capital letters are for class names.
- extract all the actions and set up a controller-class aside of that GUI-class. Make the controller the Actionlistener - you will get a much cleaner code, with much more structure.
to your questions:
1. which messege text? I can''t find which one you meant. The String msg in your function entLetter(char en) is not a displayable item.
2. you need to reload your GUI by usingthis.redraw()- you don''t need to set your buttons "false" in that case.

我有这个:
I have this:
Random ran = new Random();
int intRan = (int) (Math.floor(Math.random() * (str.length - 0 + 1)) + 1);
ranWord = new String(str[intRan]);
应该是:
Should be:
this.ranWord = str[new Random().nextInt(str.length)];
