Comparator<Person> compareByName = Comparator.comparing(Person p -> p.getName());

try (Stream<String> lines = Files.lines(Paths.get("text.txt"))) {
    long count = lines
            .flatMapToInt(String::codePoints)
            .filter(c -> !Character.isSpaceChar(c))
            .count();
    System.out.printf("Count: %d", count);
} catch (Exception e) {
    e.printStackTrace();
