Java - 扫描器不会删除所有需要的对象

Question

我正在尝试做一些'邪恶的Hang子手游戏'（漂亮的斯坦福CS演习）。游戏的目的是通过尽可能多地移除尽可能多的字词解决方案来“欺骗”，以便用户在最终结束之前无法猜测。

我已经做了一个循环（下图），似乎删除了许多单词可能的单词，但由于某种原因它并没有删除所有这些单词。输入是一个包含约120K字的dictionary.txt文件。

当我“猜”字母“a”时，它会带走大约60-70％的带有“a”的单词（基于输出与txt文件中第一对单词之间的比较进行估计）

File file = new File("dictionary.txt"); 
    Scanner textScan = new Scanner(file); 

    List<String> wordList = new ArrayList<String>(); 

    while (textScan.hasNext()) 
     { 
      word = textScan.next(); 
      wordList.add(word); 

     } 
    System.out.println("The ArrayList has " + wordList.size() + " objects stored in it."); 


    Scanner textScan1 = new Scanner(file); 

    for(int i = 0; i <= guessNumber; i++) 

    { 
     Collections.sort(wordList); 

     System.out.println("Type in your guess as a letter "); 
     String guess = keyboard.next(); 
     guess = guess.toLowerCase(); 

    while (textScan1.hasNext()) 
    { 
     String word1 = textScan1.next(); 
     if (wordLength != word1.length() && word1.contains(guess)) 
      { 
      wordList.remove(word1); 
      } 


    } 
    } 

我知道我的代码在这一点上有点混乱，我试图改进关于我的编程的一切，所以所有的反馈都非常感谢！我有一种感觉，那就是我不需要在那里等东西。

，我将发布的情况下，帮助下整个代码：

终于想通了它与扫描仪做。它必须在循环内启动

for(int i = 1; i <= guessNumber; i++) 

    { 
     Scanner textScan2 = new Scanner(file1);   
     System.out.println("Type in your guess as a letter "); 
     String guess = keyboard.next(); 
     //System.out.print(guess); 

    while (textScan2.hasNext()) 
    { 

     String word1 = textScan2.next(); 
     if (wordLength != word1.length() || (word1.contains(guess))) 
      { 
      wordList.remove(word1); 
      } 





    } 
    }
