尝试创建一个方法来显示游戏Hang Man (Java)的猜测字母

public class HangManGame {
    public static void main(String[] args) {
        String targetWord = "hangman";
        String guessedLetters = "ahmn";
        String displayedWord = showGuesses(targetWord, guessedLetters);
        System.out.println(displayedWord);
    }

    public static String showGuesses(String targetWord, String guessedLetters) {
        StringBuilder result = new StringBuilder();

        for (int i = 0; i < targetWord.length(); i++) {
            char letter = targetWord.charAt(i);
            if (guessedLetters.contains(String.valueOf(letter))) {
                result.append(letter);
            } else {
                result.append("_");
            }
        }

        return result.toString();
    }
}
