这是我的程序的大部分错误部分：
//play method
private void play() throws IOException
{
do {
guess(alphabet);
usedLetters(used, alphabet);
do {
System.out.println("You have already guessed this " + alphabet + " and the others listed above.");
guess(alphabet);
} while (letterUsed == true);//will keep asking until letter was not used
if (letterUsed == false)
{
life--;
underWord(currentWord , checkLetter, used);
} //only if the letter was not used, it will be checked for in the current word trying to be solved
if (life == 0) {
checkWord(currentWord , checkLetter);
}
} while (checkLetter != currentWord);
}
特别是这种方法目前存在所有错误。我需要询问用户对 1 个字母的猜测，然后检查它是否在他们当前试图猜测的单词中。我还存储了他们已经猜到的所有字母，以确保他们不会因为猜到同一个字母两次而丧生。所以她我有三个数组，一个存储使用过的字母，一个存储已经猜到的单词部分（以及需要 _ 的部分），一个存储他们试图猜测的单词。有没有更好的方法可以在下面编写此方法来完成所需的任务？
//underWord method to return the word with all characters not in letters replaced by _'s
private void underWord(char currentWord[] , char checkLetter[], char used[]) throws IOException //add parameters what it recieves
{
for (int i = 0; i<currentWord.length; i++) {
for (int index = 0; index<checkLetter.length; index++){
if (used.contains(currentWord.charAt(i)))
{
checkLetter[index] = currentWord.charAt(i);
}
else
{
checkLetter[index] = '_';
}
}
}
for (int i = 0; i < checkLetter.length; i++)
{
System.out.println(checkLetter[i]);
}
}//End of maskWord method
我编译并显示以下内容：

这是我第一次使用 Buffered Reader，我不知道出了什么问题
