当代码运行并且您要求 char 并键入一个字母时，让我们说“e”，输出使其成为“eeeee”，而不是在部分 word 方法中填写 e。我不知道如何解决它。我认为问题出在replaceChar方法或updatePartialWord方法中。希望得到一些帮助。谢谢！ PS即使有更简单的方法，我也需要保持方法输入相同！

// creates partialWord using string length then creating a new string with the same amount of dashes
public static String createPartialWord(String secretWord)
{
    String newsecretWord = "";
    int wordLength = secretWord.length();
    while (wordLength > 0)
    {
        newsecretWord = newsecretWord + "-";
        //System.out.print("-");
        wordLength--;
    }
    System.out.println();
    return newsecretWord;

}
//replaces character at certain ints
public static String replaceChar(String word, char c, int i)
{


     //return word.replace(word.charAt(i), c);
    String newText = word.replace(word.charAt(i), c);
    return newText;

}

public static String updatePartialWord(String partial, String secret, char c)
{


    if(c==secret.charAt(0))
    {
         return replaceChar(partial, c, 0);
    }   
    if(c==secret.charAt(1))
    {
         return replaceChar(partial, c, 1);  
    }       
    if(c==secret.charAt(2))
    {
         return replaceChar(partial, c, 2);
    }   
    if(c==secret.charAt(3))
    {
         return replaceChar(partial, c, 3);

    }   
    if(c==secret.charAt(4))
    {
         return replaceChar(partial, c, 4);
    }   



    return partial;
}

根据javadocs

返回一个新字符串，该字符串是用 newChar 替换此字符串中所有出现的 oldChar 所产生的。

public static String replaceChar(String word, char c, int i) {
    String newText = word.replace(word.charAt(i), c);
    :

在word这种情况下是-----，因此您将位置i（即-）处出现的所有字符替换为字母。

所以所有-的字符都变成了你刚刚输入的字符。

相反，您应该更改部分单词中的每个字符，当且仅当您的秘密单词中的等效字符与刚刚输入的字符匹配时，例如：

public static String replaceChar(String word, String secret, char c) {
    for (int i = 0; i < word.length(); i++) {
        if (secret.charAt(i) == c) {
            word = word.substring(0, i) + c + word.substring(i+1); 
        }
    }
    return word;
}

当然，由于您现在使用的是密语，并且字符的位置无关紧要，因此您可以更改传入的内容。调用代码可以修改为：

if (c == secret.charAt(0))
    return replaceChar(partial, secret, c);
if (c == secret.charAt(1))
    return replaceChar(partial, secret, c);
// :
// and so on.

当然，即使有这个修复，你仍然有一个问题：

System.out.println("The current partial word is: " + updatePartialWord(partialWord, secretWord, input));

这会输出由函数计算的新的部分单词，但它实际上并没有更改部分单词。你需要一些类似的东西：

partialWord = updatePartialWord(partialWord, secretWord, input));
System.out.println("The current partial word is: " + partialWord);
