我正在做这个刽子手项目，我差不多完成了，但我不能让输出显示所有正确的字母来代替下划线，而是只显示刚输入的正确字母。请帮忙。

答案 0 :(得分：1)
你应该创建一个名为lettersGuessed的变量，该变量最初是空字符串，""或ArrayList<Character>.然后在每次猜测之后，或者此行char guess = Expo.enterChar();添加char guess到您的ArrayList或String（如果您不熟悉arraylist，我建议使用字符串）lettersGuessed += guess;然后System.out.println("Letters guessed: " + lettersGuessed)。
