How to write logic for fatching start date and end date from model class

[Former Member]

Hi All, Could you help me to write correct logic for "get start date and end date from model class "

so that i can able to use dynamic date from hac through impex and from backoffice .

    final int startDate = XXXXXXXModel.getStartDate();  

   final Calendar cal = Calendar.getInstance();

   cal.add(Calendar.DAY_OF_MONTH,startDate);



  final int endDate = XXXXXXXModel.getEndDate();

   final Calendar cal = Calendar.getInstance();

   cal.add(Calendar.DAY_OF_MONTH,endDate);

Basically i need to use these dynamic date in cron job .

Regards,
