Question

我是编程和java的新手（正如你所看到的），我真的陷入编程hangman的基本问题。我的代码并不是我所知道的最干净的代码，但我真的想对逻辑明智的错误提出一些建议。我的麻烦是让程序输出＆＃39; hangman display＆＃39;每次猜测都正确。我认为我尝试错误++设置的方式存在问题。我也无法让重复的信件正常工作，但却无法弄明白。

Answer 1

    if (!letterFound)
    {
        letterFound = false;

如果!letterFound为真，则表示letterFound已为假。因此，之后无需将其设置为false。这是一个逻辑缺陷。我建议将letterFound = false;移到while循环的开头。所以你开始每一个循环。

Java Hangman无法正确循环
