Example Uses
Of Calendar Class
Write a java program that can
find your age if the current year is 2007.
This example uses the Calendar class
to compute a person's age.
// Create a calendar object with
the date of birth
Calendar dateOfBirth = new GregorianCalendar(1972,
Calendar.JANUARY, 27);
// Create a calendar object with
today's date
Calendar today = Calendar.getInstance();
// Get age based on year
int age = today.get(Calendar.YEAR)
- dateOfBirth.get(Calendar.YEAR);
// Add the tentative age to the
date of birth to get this year's birthday
dateOfBirth.add(Calendar.YEAR,
age);
// If this year's birthday has not
happened yet, subtract one from age
if (today.before(dateOfBirth)) {
age--;
}
