java - 我的 java bmi 计算器给出相同的答案

Question

我正在尝试制作一个 bmi 计算器，但答案总是一样。

我试着输入数字 height=1.50 meter weight=100 kg但答案是体重不足

public static void main(String[] args) {
    Scanner sc = new Scanner(System.in);
    double bmi = 0;
    double weightinkg = 0;
    double heightinmeter = 0;
    String status = "";
    System.out.println("Enter the weight in Kg :");
    weightinkg = sc.nextDouble();
    System.out.println("Enter the height in Meter : ");  //enter the age
    heightinmeter = sc.nextDouble();
    if ((weightinkg <= 0) && (heightinmeter <= 0))
        System.out.println("ERROR: Negative number");
    double square = Math.pow(heightinmeter, 2);
    bmi = weightinkg / heightinmeter;
    if (bmi >= 0) {
        if (bmi >= 0 && bmi <= 24) {
            status = "Under Weight";
        } else if (bmi >= 25 && bmi <= 29) {
            status = "Healthy";
        } else if (bmi >= 30 && bmi <= 34) {
            status = "Overweight";
        } else
            status = "Obese";
    }
    else
        System.out.println("Invalid BMI (number must be positive");
    System.out.printf("Hello, your status is %s ! Please come again!", status);
}

Answer 1

您没有使用正方形。应该是

    double square = Math.pow(heightinmeter, 2);
    bmi = weightinkg / square;
