Month is not printed from a date - Java DateFormat

Question

How to get month from a date in java :

        DateFormat inputDF  = new SimpleDateFormat(\"mm/dd/yy\");
        Date date1 = inputDF.parse(\"9/30/11\");

          


        

Answer 1

First, you used mm in your date format, which is "minutes" according to the Javadocs. You set the minutes to 9, not the month. It looks like the month defaults to 0 (January).

Use MM (capital 'M's) to parse the month. Then, you will see 8, because in Calendar months start with 0, not 1. Add 1 to get back the desired 9.

The first month of the year in the Gregorian and Julian calendars is JANUARY which is 0

// MM is month, mm is minutes
DateFormat inputDF  = new SimpleDateFormat("MM/dd/yy");  

and later

int month = cal.get(Calendar.MONTH) + 1; // To shift range from 0-11 to 1-12
