Can anyone solve my problem...?😭

Question about the task

Under discussion

My Output Is Correct. Still It Shows Too Many Requirements Not Met. Please Anyone Tell Me, What's The Issue With My Code?

Use the keyboard to enter three integers. Display the number of positive numbers and the number of negative numbers in the original set, in the following form:
"Number of negative numbers: a" and "Number of positive numbers: b", where a and b are the unknowns.

Here are some examples:
a) if you enter the numbers
2
5
6
then we display
Number of negative numbers: 0 Number of positive numbers: 3

b) if you enter the numbers
-2
-5
6
then we display
Number of negative numbers: 2 Number of positive numbers: 1

Requirements:

The program should read the numbers from the keyboard.
The program should display text on the screen.
The program should display the number negative numbers in the original set.
The program should display the number of positive numbers in the original set.
If there are no negative numbers, the program should display "Number of negative numbers: 0".
If there are no positive numbers, the program should display "Number of positive numbers: 0".
Note that 0 is not a positive or negative number.

Notice the different: "Number of negative number: " // your code "Number of negative numbers: " // requirements

try to remove the else... it refers to the last if condition and makes that 'Number of negative number:' just gets printed if c >= 0. And you should recheck the text you output. It has minor discrpancies compared to the requirements.

I REMOVED ELSE PART STILL IT SHOWS REQUIREMENTS NOT MET. MY CODE RUNS ABSOLUTELY FINE.

package com.codegym.task.task04.task0429;

/*
Positive and negative numbers

*/

import java.io.IOException;
import java.io.BufferedReader;
import java.io.InputStreamReader;

public class Solution {
    public static void main(String[] args) throws Exception {
        //write your code here
        BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));

        int a = Integer.parseInt(reader.readLine());
        int b = Integer.parseInt(reader.readLine());
        int c = Integer.parseInt(reader.readLine());

         int greater = 0;
         int smaller = 0;

        if(a>0)
            greater++;
        if(b>0)
            greater++;
        if(c>0)
            greater++;
        if(a<0)
            smaller++;
        if(b<0)
            smaller++;
        if(c<0)
            smaller++;
        System.out.println("Number of negative number: " + smaller);
        System.out.println("Number of positive number: " + greater);
    }
}

No it doesn't. Reread my first post. Removing the else is just one part of the solution (number != numbers).

Requirements ask you to output the result: in the following form: "Number of negative numbers: a" and "Number of positive numbers: b" But you output for eg. negative numbers: Number of negative number: again the requirements.. Number of negative numbers: The validator is very picky about such details and other commenters already told you about that (Gellert Varga). I don't know how to make it more clear that a 's' is missing in your output.
