I do not understand what is wrong with my code it works ok on my PC:

    public static void main(String[] args) throws IOException {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in, "ISO-8859-1"));
        char[] buffer = new char[262144];
        br.read(buffer);
        Scanner in = new Scanner(new String(buffer));
        Stack<String> lifo = new Stack<String>();
        DecimalFormat format = new DecimalFormat("0.00000", new DecimalFormatSymbols(Locale.US));
        while (in.hasNextLong()) {
            lifo.push(format.format(Math.sqrt(in.nextLong())));
        }
        while(!lifo.empty()){
            System.out.println(lifo.pop());
        }
    }

Could someone explain it to me ?
