我算投机取巧吗？

import java.util.*;

public class Main {

    public static void main(String[] args) {
        Scanner s = new Scanner(System.in);
        double add = 0;//正整数合
        int fu = 0;//负数个数
        int count = s.nextInt();
        int all = 0;
        while (count > 0){
            int i = s.nextInt();
            if (i < 0){
                fu++;
            }else {
                if (i != 0){
                    all++;
                }
                add += i;
            }
            count--;
        }
        if (all == 0){
            System.out.println(fu+" "+"0.0");
        }else{
            System.out.println(fu+" "+String.format("%.1f",add/all));
        }
    }
}
