    Or for short:

    import java.util.Scanner;

    public class Solution {

    public static void main(String[] args) {
    Scanner in = new Scanner(System.in);
    final int n = in.nextInt();
    final float[] count = new float[3];

    for (int i=0;i<n;i++) {
        count[1+Integer.signum(in.nextInt())]++;
    }
    System.out.printf("%.6f %n",count[2]/n);
    System.out.printf("%.6f %n",count[0]/n);
    System.out.printf("%.6f %n",count[1]/n);
}

    }
