当代码运行并且你要求char并输入一个字母时，让我们说“e”输出使它成为“eeeee”而不是填写部分单词方法中的e。我不确定如何解决它。我认为问题出在 replaceChar 方法或 updatePartialWord 方法中。会爱一些帮助。谢谢！ P.S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;
}

根据javadocs
返回替换所有出现次数所产生的新字符串 带有newChar的字符串中的oldChar。
答案 1 :(得分：0)
public static String replaceChar(String word, char c, int i) {
String newText = word.replace(word.charAt(i), c);
:
在这种情况下，word为-----，因此您要用字母替换位置i（即-）中所有出现的字符。
因此，所有-个字符都会成为您刚输入的字符。
当且仅当 secret 单词中的等效字符与刚刚输入的字符匹配时，您应该改变部分单词中的每个字符，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，由于你现在正在使用密码并且字符的位置无关紧要，你可以改变传入的内容。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，即使使用进行修复，您仍然会遇到问题：
System.out.println("The current partial word is: " + updatePartialWord(partialWord, secretWord, input));
这将输出由函数计算的新部分单词，但实际上不会更改部分单词。你需要的东西是：
partialWord = updatePartialWord(partialWord, secretWord, input));
System.out.println("The current partial word is: " + partialWord);
