java我正在开发一个RNG猜测游戏，生成器一直保留110的包含集界限

Question

我正在为我的CS课程介绍编写一个RNG猜测游戏，进展顺利。在它完成之前，我现在唯一的问题是，有时我测试代码，在easy模式下输入一个像5这样的整数，它表示太高，所以我一次降低一个inter到1，这应该是最低界限，但它仍然表示太高。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，以便我知道以备将来参考？谢谢

如果你的情况不对。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.");
}
