Can someone check my code and tell me where I'm wrong?
package com.codegym.task.task05.task0507;
/*
Arithmetic mean
*/
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));
double sum = 0;
int count = 0;
double mean =0;
while (true)
{
int num = Integer.parseInt(reader.readLine());
if (num == -1)
{
break;
}
else if (num != 0)
{
count++;
sum += num;
}
}
mean = sum/count;
System.out.println(mean);
}
}
