Answer 1

This works Perfectly.....

public int getAge(int DOByear, int DOBmonth, int DOBday) {

        int age;

        final Calendar calenderToday = Calendar.getInstance();
        int currentYear = calenderToday.get(Calendar.YEAR);
        int currentMonth = 1 + calenderToday.get(Calendar.MONTH);
        int todayDay = calenderToday.get(Calendar.DAY_OF_MONTH);

        age = currentYear - DOByear;

        if(DOBmonth > currentMonth) {
            --age;
        } else if(DOBmonth == currentMonth) {
            if(DOBday > todayDay){
                --age;
            }
        }
        return age;
    }
