简单的一个if分支

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        double height = scanner.nextDouble();
        double weight = scanner.nextDouble();

        //write your code here......
        double num = weight/(height*height);
        if(num>=24.9){
            System.out.println("偏胖");
        }else if(num>=20.9){
            System.out.println("适中");
        }else if(num>=18.5){
            System.out.println("苗条");
        }else{
            System.out.println("偏瘦");
        }

    }
