三目运算符解法

来个看起来高级一点的写法，抛弃了多重ifelse

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        double height = scanner.nextDouble();
        double weight = scanner.nextDouble();
    double ibm=weight/(height*height);
      
        String i=ibm<18.5?"偏瘦":ibm<20.9?"苗条"
            :ibm<24.9?"适中":"偏胖";
        //write your code here......
        System.out.println(i);

    }
}
