我对Java编码非常陌生，我已经在这个问题上工作了大约4天。我在编一个你自己选择的结局故事。当我到达第69行时，如果读者选择是，我希望系统重新开始故事，如果他们选择否，则结束程序。我不确定我是否正确地编写了while循环或者我是否可以使用break;就像我在使用它一样。抱歉我的代码太丑了，哈哈，我正在努力做得更好。任何建议都是感激的!

Scanner.nextBoolean()期望True或False(不区分大小写)，而不是Yes/No
public static void main(String[] args) {
Scanner s = new Scanner("yes");
//s.nextBoolean() throws an InputMismatchException
System.out.println(s.nextBoolean());
