扫描器引发的公共类InputMismatchException，以指示检索的令牌与预期类型的模式不匹配，或令牌超出预期类型的范围。
看看下面的答案:https://stackoverflow.com/a/14027583/7421645，并试着理解为什么要获得异常，例如，尝试捕获异常：
try {
// ...
} catch (InputMismatchException e) {
System.out.print(e.getMessage()); //try to find out specific reason.
}
我还会尝试先将测试数据作为字符串输入，至少直到您确定预期的输入提供预期的输出为止。
String input = "1 fish 2 fish red fish blue fish";
Scanner s = new Scanner(input);
