Java程序来计算体重指数(BMI)
体重指数是以千克为单位的体重除以以米为单位的身高的平方。表示为kg/m^2。
给出了一个计算体重指数(BMI)的程序。
示例
import java.util.Scanner;
public class Example {
public static void main(String args[]) {
Scanner sc = new Scanner(System.in);
System.out.print("Input weight in kilogram: ");
double weight = sc.nextDouble();
System.out.print("\nInput height in meters: ");
double height = sc.nextDouble();
double BMI = weight / (height * height);
System.out.print("\nThe Body Mass Index (BMI) is " + BMI + " kg/m2");
}
}输出结果
Input weight in kilogram: 55 Input height in meters: 1.5 The Body Mass Index (BMI) is 24.444444444444443 kg/m2
现在让我们了解上面的程序。
重量和高度的值分别从用户以千克和米为单位获得。证明这一点的代码片段如下所示-
Scanner sc = new Scanner(System.in);
System.out.print("Input weight in kilogram: ");
double weight = sc.nextDouble();
System.out.print("\nInput height in meters: ");
double height = sc.nextDouble();然后，使用公式BMI=体重/（身高*身高）来计算体重指数。最后，显示“体重指数”的值。证明这一点的代码片段如下-
double BMI = weight / (height * height);
System.out.print("\nThe Body Mass Index (BMI) is " + BMI + " kg/m2");
