我正在用Java制作适用于大学课程的Hangman游戏，但是我的代码有问题。我已经运行并打开它，但是当我在文本框中输入字母进行猜测时，出现此错误：

基于列表中的第一个错误，我怀疑这与这段代码有关：
do
{
if (playerGuess.equals(arrayToGuess[c]))
{
correct = true;
lettersToGet[c] = playerGuess;
}
c++;
}
while (c < 6);
c = 0;
进一步来说：
if (playerGuess.equals(arrayToGuess[c]))
我不知道这有什么问题，因为这是我第一次使用String数组并将数组每个部分的字符与用户输入的内容进行比较。希望有人能帮忙。如果您需要更多信息，请告诉我，我们会尽快与您联系。我还创建了一个短期Pastebin，以便可以查看整个代码以帮助发现问题：Pastebin Link
谢谢
最佳答案
您的问题出在split方法上-它用reqexp分割字符串，点具有特殊含义，您必须设置
String breaker = "[.]";
要么
String breaker = "\\.";
顺便说一句：如果需要获取字符串的第i个字符，则可以使用
s.charAt( i )，并且不需要split ;-)
