Java华氏转摄氏

package test;

import java.util.Scanner;

public class temperature {

    public static void main(String[] args) {
        double input_hs;
        double res;
        System.out.println("请输入华氏数值:");
         Scanner input = new Scanner(System.in);
         input_hs=input.nextDouble();
         change c=new change();
         res=c.compute(input_hs);
         System.out.print("摄氏度是:"+res);
    }

}
class change{
    double compute(double hs){
        double ss=0.0;
        ss=(5.0/9)*(hs-32);
        return ss;
    }

}
结果
请输入华氏数值:
100
摄氏度是:37.77777777777778
