当程序启动时，程序会要求玩家在1和2之间进行选择，1如果你想猜 secret 单词，2如果你想猜字母。当我按 2 时，程序运行得很好，但当我按 1 时，程序会要求玩家按预期输入他/她猜测的单词。如果猜测的单词与 secret 单词匹配，则可以正常工作，但问题是，如果玩家输入了错误的猜测单词，则不会显示要求玩家按 1 猜测单词或按 2 猜测字母的菜单。它只是要求玩家再次猜测 secret 单词。

                // check the arrayList to eliminate duplicates
                if (containerForChars.contains(typedLetter)) {
                    System.out.println("You have already tried that letter");
                    continue;
                }
                containerForChars.add(typedLetter); 

                if (word.contains(typedLetter + "")) {
                    for (int y = 0; y < word.length(); y++) {
                        if (word.charAt(y) == typedLetter) {
                            yourWord[y] = typedLetter;

Answer 1

据我所知，问题在于你总是停留在

while (remainingGuess > 0)

在 checkTheWord 方法中循环。如果输入的单词不正确，则继续循环，直到没有剩余的尝试为止。 由于您在静态 guessTheWord 方法中调用 checkTheWord 方法后中断，因此程序也将始终在此之后终止。您可能应该在使用该方法后继续，而不是在 checkTheWord 方法中循环，因为 guessTheWord 中的循环无论如何都具有相同的循环条件。
