age compute using calendar class [problem]

[scias23]

i just can't figure out what's wrong with this.

1. suppose i enter 9-3-1991 as the birthdate, this should return 18. but it returns 17. //wrong
2. suppose i enter 2-9-1991 as the birthdate, this returns 18. //correct

what's wrong with my code?

    private static int ageCalc(int mm, int dd, int yyyy) {
 
        Calendar currentDate = Calendar.getInstance();
        Calendar birthDate = new GregorianCalendar();
 
        birthDate.set(yyyy, mm, dd);
 
        age = currentDate.get(Calendar.YEAR) - birthDate.get(Calendar.YEAR);
 
        birthDate.add(Calendar.YEAR, age);
 
        if(currentDate.before(birthDate)) {
            age--;
        }
 
        return age;
    }

take a look at your before method. That appears to be the source of the error: it the date is on or before the current date then the method should return a false or don't reduce age message. Or if before OR same ...
