我正在开发一个 RNG 猜谜游戏，生成器一直将包含集限制为 1-10

Question

我正在编写一个RNG猜谜游戏作为我的CS入门课程，并且进展顺利。唯一的问题是，在我测试代码的时候，有时候我在简单模式下输入一个整数，比如5，它说太高了，所以我每次降低一个中间值到1，这应该是最小的边界，它仍然说太高了。是否有人愿意找到我在代码中遗漏的错误，并向我解释为什么这是一个错误，以及更好的方法来处理它，以便我知道将来的参考?谢谢!

您的if-condition错误。你告诉用户，这个数字太高了，而实际上它太低了:

if(e < userNum) {
    System.out.println("Your guess is too high, please try again.");
}
