将两个日期之间的月日输出到List中

private static List<String> getMonthBetween(String minDate, String maxDate) throws ParseException {
        ArrayList<String> result = new ArrayList<String>();
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");//格式化为年月

        Calendar min = Calendar.getInstance();
        Calendar max = Calendar.getInstance();

        min.setTime(sdf.parse(minDate));
        min.set(min.get(Calendar.YEAR), min.get(Calendar.MONTH), 1);

        max.setTime(sdf.parse(maxDate));
        max.set(max.get(Calendar.YEAR), max.get(Calendar.MONTH), 2);

        Calendar curr = min;
        while (curr.before(max)) {
         result.add(sdf.format(curr.getTime()));
         curr.add(Calendar.MONTH, 1);
        }

        return result;
    }
