I don´t understand where is the problem in my task. Do you help me to find it?
package com.codegym.task.task04.task0416;

Crossing the road blindly

import java.io.*;
public class Solution {
public static void main(String[] args) throws Exception {
//write your code here
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
String number = reader.readLine();
double dNumber = Double.parseDouble(number);
if (dNumber % 3 == 0) System.out.println("yellow");
else if (dNumber % 4 == 0) System.out.println("red");
else System.out.println("green");
}
}
