而不是使用布尔java循环

Question

我对Java编码非常陌生，我已经研究这个问题大约4天了。我正在做一个选择你自己的结局故事。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码了while循环，或者我甚至可以使用中断；操作员就像我在使用它一样。对不起，我的代码太难看了，哈哈，我正在努力变得更好。感谢您的建议！

https://docs.oracle.com/javase/7/docs/api/java/util/Scanner.html#hasNextBoolean()

Scanner.nextBoolean（）需要True或False（不区分大小写），而不是是/否

public static void main(String[] args) {
    Scanner s = new Scanner("yes");

    //s.nextBoolean() throws an InputMismatchException
    System.out.println(s.nextBoolean());
}
