BMI（身体健康指数）nextInt()的弊端

摘要: nextInt()的弊端

import java.util.Scanner;

public class BMT {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int pounds, feet, inches;
double heightMeters, mass, BMI;
System.out.println("Enter your weight in pounds.");
pounds = sc.nextInt();
System.out.println("Enter your height in feet followed");
System.out.println("by a space then additional inches.");
feet = sc.nextInt();
inches = sc.nextInt();
heightMeters = ((feet * 12) + inches) * 0.0254;
mass = (pounds / 2.2);
BMI = mass / (heightMeters * heightMeters);
System.out.println("your BMI is " + BMI);
System.out.println("your risk category is ");
if (BMI < 18.5) {
System.out.println("Underweight.");
} else if (BMI < 25) {
System.out.println("Normal weight.");

}else if(BMI<30){
System.out.println("Overweight.");
}else{
System.out.println("Obese.");
}
}
