Answer 1

private String getAge(int year, int month, int day){

  Calendar dob = Calendar.getInstance();

  Calendar today = Calendar.getInstance();

  dob.set(year, month, day);

  today.set(today.get(Calendar.YEAR), today.get(Calendar.MONTH) + 1,
    today.get(Calendar.DATE));

  int age = today.get(Calendar.YEAR) - dob.get(Calendar.YEAR);

  if (today.get(Calendar.DAY_OF_YEAR) < dob.get(Calendar.DAY_OF_YEAR)) {

    age--;

  }

  Integer ageInt = new Integer(age);

  String ageS = ageInt.toString();

  return ageS;
}
