public static List<String> getDateArrByMonth(String dateStart, String dateEnd) throws ParseException {
    SimpleDateFormat sdf = new SimpleDateFormat("yyyyMM");
    Date startDate = sdf.parse(dateStart);
    Date endDate = sdf.parse(dateEnd);
    Calendar c = Calendar.getInstance();
    List<String> list = new ArrayList<String>();
    SimpleDateFormat df = new SimpleDateFormat("yyyyMM");
    for (; startDate.getTime() <= endDate.getTime(); ) {
        String _startDate = df.format(startDate);
        list.add(_startDate);
        c.setTime(startDate);
