items.stream()
.filter(s->s.contains("B"))
.forEach(System.out::println);User user1 = new User("James", "Gosling", 63);

List<User> userList = Arrays.asList(user1, user2, user3);
userList.stream().filter(user -> (user.getSurname().contains("a") && (user.getAge().equals(65))) ).collect(Collectors.toList()).forEach(System.out::println);
