  static Logger logger = LoggerFactory.getLogger(DateCalculate.class);

  
  public static List cutDate(String dateType, String start, String end) {
    try {
      SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
      Date dBegin = sdf.parse(start);
      Date dEnd = sdf.parse(end);
      return findDates(dateType, dBegin, dEnd);
    } catch (Exception e) {
      logger.error(e.getMessage(), e);
    }
    return null;
  }

  public static List findDates(String dateType, Date dBegin, Date dEnd) throws Exception {
    List listDate = new ArrayList<>();
    Calendar calBegin = Calendar.getInstance();
    calBegin.setTime(dBegin);
    Calendar calEnd = Calendar.getInstance();
    calEnd.setTime(dEnd);
    while (calEnd.after(calBegin)) {
      switch (dateType) {
 case "M":
   calBegin.add(Calendar.MONTH, 1);
   break;
 case "D":
   calBegin.add(Calendar.DAY_OF_YEAR, 1);break;
 case "H":
   calBegin.add(Calendar.HOUR, 1);break;
 case "N":
   calBegin.add(Calendar.SECOND, 1);break;
      }
      if (calEnd.after(calBegin))
 listDate.add(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(calBegin.getTime()));
      else
 listDate.add(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(calEnd.getTime()));
    }
    return listDate;
  }


  public static void main(String[] args) {
    String start = "2016-02-01 00:00:00";
    String end = "2016-03-02 00:00:00";
    List list = cutDate("D", start, end);
    for (String str :list){
      System.out.println(str);
    }
