java - Hangman Java 游戏打印错误和正确的猜测

Question

我正在使用我的第一种编程语言 Java，但我无法正确猜测以正确打印。当输入错误的字母时，它会打印“错误!”但是当猜到正确的字母时，它会打印“正确!”和“错误!”...任何帮助表示赞赏。谢谢。 :)
这些单词是从数组中提取的。

    System.out.println("The word to guess is represented by a row of dashes, representing each letter of the word.");
    System.out.println("If you guess a letter correctly, it replaces a dash and you can continue to guess until the word is uncovered.");

Answer 1

这一段代码:

for (int i = 0; i < word2Char.length; i++){
        if (guess == word2Char[i]){
           wordLength[i] = word2Char[i];
           letterFound = true;
           correctGuesses++;
           System.out.println("Correct!");
        }


    }
       if(!letterFound){
        wrongGuesses++;
    System.out.println("Wrong!");
       }

需要是这样的:

for (int i = 0; i < word2Char.length; i++){
                if (guess == word2Char[i]){
                   wordLength[i] = word2Char[i];
                   letterFound = true;
                   break;
                }else{
                    letterFound = false;
                }
            }
               if(letterFound == false){
                    wrongGuesses++;
                    System.out.println("Wrong!");
               }else{
                   correctGuesses++;
                   System.out.println("Correct!");
               }

问题是在 for 循环中，即使 letterFound 为 true，循环也会继续检查每个字符。只有当有人正确猜出最后一个字符时它才会起作用。因此，我所做的是添加一个 break 语句，以便每当 letterFound 为 true 时，for 循环就会退出。
