 {

    Date dt = new Date();
    System.out.println(dt);

        List dates = getDates("2017-01-01",dateFormat.format(new Date()));
        //IF you don't want to reverse then remove Collections.reverse(dates);
         Collections.reverse(dates);

        fromCal.setTime(dateFormat .parse(fromDate));

        Calendar toCal = Calendar.getInstance();
        toCal.setTime(dateFormat .parse(toDate));

        while(!fromCal.after(toCal))
        {
            dates.add(fromCal.getTime());
            fromCal.add(Calendar.DATE, 1);
