Here is an example that displays the date of all the thursdays of the given year.

import java.util.*;
import java.text.*;

public class GetDateFromDay{

   public String getDateOfWeekDay(int weekId, int year, int weekDay){
        Calendar cal = Calendar.getInstance();
        cal.set(Calendar.YEAR, year);
        cal.set(Calendar.WEEK_OF_YEAR, weekId);
        cal.set(Calendar.DAY_OF_WEEK, weekDay);

        SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy");
        System.out.println(sdf.format(cal.getTime())); 
        return  sdf.format(cal.getTime());    
       }
        public static void main(String args[]){
        GetDateFromDay dt = new GetDateFromDay();
        for (int weekCount = 1; weekCount <= 53; weekCount++) {
        dt.getDateOfWeekDay(weekCount,2012,Calendar.THURSDAY);
      }
    }
}

But I have a problem here

My Frequency Start Date is 24-08-2012

My frequency end date - not defined

Calculation Frequency is Weekly(Sunday)

My calculation will be from 24-08-2012 to the following sunday

My question is how to find the following date of sunday
