calculate age

[esokol]

Is there an easy way to calculate number of years using standard
Java? I have seen some examples but they use a product using
BigDate. I need something that will calculate number of years taking
into account leap years.

Thanks
Elly

Could you give an example of exactly what you mean by
"calculate number of years?"

From some old code:

private static int age(int y, int m, int d) {
Calendar cal = new GregorianCalendar(y, m, d);
Calendar now = new GregorianCalendar();
int res = now.get(Calendar.YEAR) - cal.get(Calendar.YEAR);
if((cal.get(Calendar.MONTH) > now.get(Calendar.MONTH)) ||
(cal.get(Calendar.MONTH) == now.get(Calendar.MONTH) &&
cal.get(Calendar.DAY_OF_MONTH) >
now.get(Calendar.DAY_OF_MONTH))) {
res--;
}
return res;
}

changing from y m d to Date is left as an exercise.

The subject line gives some hints to what it could mean.
