好的，这是我的第一个Java项目。我很高兴它终于成功了，特别是因为我花了很多时间在我想不到的时间内。
我有3个问题
我必须在所有方法共享的变量前面放置“静态”，因为如果没有它，我将遇到“无法从静态内容引用非静态变量”错误。它如何影响我的脚本，在实践中有什么意义？
为什么我不能更改软件包名称？除了脚本的第一行之外，没有其他地方提到它
游戏可以正常运行，但是我忘了一件事，而且我真的不知道如何解决这个问题。
这部分决定玩家是否获胜
if (wordList.size() == 6) {
System.out.println("\nYou won, congratulations! \n");
break;
}
问题是，我不得不写数字“ 6”，因为我承认在我的代码字“经济”中有2个字母“ o”，所以是否可以这样写？
wordList.size() == word.length()
它不起作用（如果代码字中没有两个相同的字母，它将起作用）
完整代码：
