如何在Java中的单个if语句中使用大于和小于 [英] how to use greater than and less than in a single if statement in java

问题描述

我已经通过编程从编程中获得了BMI计算器，我要做的一件事就是使用if语句添加类别.体重为18.5到24.9正常体重，所以这是其中一类.

I have made a BMI calculator from programming by doing, one of the thing i have to do is add categories using if statements. 18.5 to 24.9 normal weight so that would be one of the categories.

这是我试图做到的方式.

This is the way i have tried to do it.

else if ( (bmi >18.5) && (<24.9))

显然这对我不起作用，我应该怎么写呢?我觉得有一种写18.5到24.9的方法，而不是使用大于或等于，但是老实说，我什至不知道要查找什么.

Obviously this won't work for me, what way should I write this I feel like there is a way to write 18.5 to 24.9 instead of using greater than or equal to but I honestly don't even know what to look up.

非常感谢您的帮助.

推荐答案

使用

if ( bmi > 18.5 && bmi < 24.9)

不幸的是，Java不支持' BETWEEN '运算符(例如 SQL 所执行的操作).

Unfortunately, Java does not support a 'BETWEEN' operator (like what SQL does e.g).
