Here is an example using http://joda-time.sourceforge.net/

import org.joda.time.Period;

public class Main{
  public static void main(String[] args) {
      DateTime start = new DateTime(2008, 2, 8, 0, 0, 0, 0);
      DateTime end = new DateTime();
      Period period = new Period(start, end);
      System.out.println(" user is " + period.getYears() + " years " + period.getMonths() + " months old");
  }
}

Have a look at http://joda-time.sourceforge.net/ - it's got a pretty nice API. I was using it the other week to do some work with dates. Hopefully it'll have what you need.
