How to find Date Difference in Months using Java ?

       

      public static int getMonthsDiffArray(Date startDate, Date endDate) {
        int[] months = null;
        Calendar startCalendar = new GregorianCalendar();
        startCalendar.setTime(startDate);
        Calendar endCalendar = new GregorianCalendar();
        endCalendar.setTime(endDate);
        int diffInMonths =
            endCalendar.get(Calendar.MONTH) - startCalendar.get(Calendar.MONTH);     
        return diffInMonths;
 }

    //HH converts hour in 24 hours format (0-23), day calculation
            SimpleDateFormat format =
                new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");
            Date startDate = format.parse("04/14/2012 09:29:58");
            Date endDate = format.parse("08/15/2012 10:31:48");
