How to get month number from month string in Java?

I've got this string

23/Gennaio/2014

and I need this other string

23/01/2014

I tried using joda.time:

DateTimeFormatter format =  DateTimeFormat.forPattern("dd/MMM/yyyy").withLocale(Locale.ITALY);
DateTime instance = format.parseDateTime("23/Gennaio/2014");  
String month_number = String.valueOf(instance.getMonthOfYear());

But I get this exception:

01-06 13:31:55.341: E/AndroidRuntime(1116): java.lang.IllegalArgumentException: Invalid format: "23/Gennaio/2014"

What am I missing?

Solution

  • It seems to expect the month name in lower case (not sure why):

    DateTime instance = format.parseDateTime("23/Gennaio/2014".toLowerCase(Locale.ITALIAN));

    should work better.
