Difference of Two Dates

[jboy]

Hi,

I am using the GregorianCalender class and I was just wondering how to get the difference of two dates. For example the difference between
3/3/2009 and 1/1/2009 should be shown like this: 2/2/0

Thank you!

What have you tried so far?

I have tried this but I don't know how to put the 10/10/2010 in a way that can be subtracted, sdf.format(date.getTime()) has 12/12/2012.

long difference = sdf.format(date.getTime()) - 10/10/2010;

GregorianCalendar and Calendar (on which the former is based) have methods that can help you here, especially the get(int field) method. If you look at the beginning of the GregorianCalendar API you'll even see sample code that shows how to use the get method. Have a look and give it a try.
