我正在创建一个刽子手程序，但我在使用单词更新方法时遇到了一些问题

Question

当代码运行时，您要求输入字符并键入一个字母，让我们说 'e' 输出使其成为 "eeeee" 而不是在部分单词方法中填写 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。会喜欢一些帮助。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;

}

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;
}

Answer 1

根据 javadocs

Returns a new string resulting from replacing all occurrences of oldChar in this string with newChar.

Answer 2

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

本例中的 word 是 -----，因此您要用该字母替换位置 i（即 -）出现的所有字符。

因此所有 - 个字符都将成为您刚刚输入的字符。

当且仅当 secret 单词中的等效字符与刚刚输入的字符匹配时，您应该改为更改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，既然你现在使用的是密字，字符的位置无关紧要，你就改变传入的内容。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，即使用修复了，你仍然有问题：

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

这会输出函数计算出的新部分单词，但它实际上并没有改变部分单词。您需要以下内容：

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