        LocalDate end = LocalDate.now().with(TemporalAdjusters.lastDayOfMonth());
        long days = Duration.between(start.atStartOfDay(), end.atStartOfDay()).toDays();
        List<String> lst = new ArrayList<>();
        for (int i = 0; i <= days; i++) {
            lst.add(start.plusDays(i).format(DateTimeFormatter.ofPattern("yyyy-MM-dd")));
        }
        lst.forEach(System.out::println);
    }
