键盘上输入体重和身高计算BMI是否超标
import java.util.Scanner;
public class BMI {
public static void main(String[] args) {
double radius;
double BMI;
Scanner input = new Scanner(System.in);
System.out.print(“体重（KG）：”);
radius = input.nextDouble();
System.out.print(“身高（M）：”);
double tall = input.nextDouble();
BMI = radius / (tall * tall);
System.out.print("身体质量指数 = " +BMI);
}
}
