爪哇Hang子手不會正確地循環

Question

我對編程和Java非常新穎（正如你所看到的），並且在編程hang子手時遇到了一個基本問題。我的代碼並不是我所知道的最乾淨的，但我真的很想在我的錯誤邏輯明智的地方輸入一些信息。我的麻煩是讓程序在猜測中正確輸出'hangman display'。我認爲有一個問題，我嘗試了錯誤的++設置。我也無法得到重複的信件正常工作，但不能完全弄清楚。

    }; 
    String[] words = 
    { 
     "javascript", "declaration", "object", "class", "failing" 
    }; 
    int randomIndex = (int) (Math.random() * words.length); 
    String randomWord = words[randomIndex]; 
    char[] explodedWord = explode(randomWord); 
    char[] censoredWord = new char[randomWord.length()]; 
    int triesWrong = 0;

    boolean letterFound = false;

    { 
     censoredWord[i] = '_';

Answer 1

if (!letterFound) 
    { 
     letterFound = false; 

如果!letterFound是事實，就意味着letterFound已經是假的。所以之後不需要將其設置爲假。這是一個邏輯缺陷。 我建議將letterFound = false;移動到while循環的開始位置。所以你每個循環都開始新鮮。
