Not sure what Im doing wrong. I think Im not reading in the list correctly.
Ignore the test tab, I created that in IntelliJ to try to test it.
package com.codegym.task.task13.task1326;

public class Solution {
public static void main(String[] args) {
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
BufferedReader fileReader = new BufferedReader(new InputStreamReader(new FileInputStream(reader.readLine())));
ArrayList<Integer> nums = new ArrayList<Integer>();
Integer line = Integer.parseInt(fileReader.readLine());
while (line != null) {
nums.add(line);
line = Integer.parseInt(fileReader.readLine());
}
Collections.sort(nums);
for (int i = 0; i < nums.size(); i++) {
if (nums.get(i) % 2 == 0) System.out.println(nums.get(i));
}
fileReader.close();
reader.close();
}
catch (Exception e){
e.printStackTrace();
}
}
