Строк правильное количество, в чем проблема?

public class Solution {
    public static void main(String[] args) throws IOException {
        // напишите тут ваш код
        Scanner scanner = new Scanner(System.in);
        FileInputStream fileInputStream = new FileInputStream(scanner.nextLine());
        ArrayList<Integer> arrayList = new ArrayList<>();

        while (true) {
            int i = fileInputStream.read();
            if (i == -1) break;

            if (Character.getNumericValue(i) != -1 & (Character.getNumericValue(i) % 2 ==0))
            arrayList.add(Character.getNumericValue(i));
        }
        fileInputStream.close();

        arrayList.sort(Comparator.naturalOrder());


        for (int xxx: arrayList) {
            System.out.println(xxx);
        }

    }
}
