try {
while (stream.available() > 0) {
int i = Integer.parseInt(fileInputStream.readLine());
list.add(i);
stream.close();
}
fileInputStream.close();
reader.close();
} catch (Exception e) {
System.out.println(e);
}
Collections.sort(list);
for (int num : list) {
if (num % 2 == 0) System.out.println(num);
}
