            calendar.add(Calendar.DAY_OF_MONTH, 30); // add 30 days
            int days = calendar.get(Calendar.DAY_OF_MONTH); // get the days plus 30 days....but I am not getting the new date with 30 days added
 
            if (days != 1) { 
                calendar.add(Calendar.MONTH, 0);
                calendar.set(Calendar.DAY_OF_MONTH, 1);

I suppose you should use calendar.add(Calendar.DAY_OF_YEAR, 30 ),
as Calendar.DAY_OF_MONTH must be getting overflow from it's max value.
