public class ABC {public static void main(String[] args) throws ParseException {String begin = "2011-02-02";String end = "2011-03-23";int step = 30;List<String> list = getJulianDays(begin, end, step);for (String date : list) {System.out.println(date);}}private static List<String> getJulianDays(String beginDate, String endDate,int step) throws ParseException {List<String> dateList = new ArrayList<String>();Calendar cal = Calendar.getInstance();SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");SimpleDateFormat sdf2 = new SimpleDateFormat("yyyyMMdd");Date start = sdf.parse(beginDate);int end = Integer.parseInt(sdf2.format(sdf.parse(endDate)));cal.setTime(start);while (Integer.parseInt(sdf2.format(cal.getTime())) <= end) {dateList.add(sdf.format(cal.getTime()));cal.add(Calendar.DATE, step + 1);}return dateList;}}

测试两个日期之间的需要获取的数据

结果：

2011-02-022011-03-05
