Answer 1

None of the posted solutions worked for me. So, I worked my own logic and got this, which works 100% for me:

 Integer getAge(Integer year, Integer month, Integer day) {
     Calendar dob = Calendar.getInstance();
     Calendar today = Calendar.getInstance();

     dob.set(year, month, day);
     int age = today.get(Calendar.YEAR) - dob.get(Calendar.YEAR);

     if(month == (today.get(Calendar.MONTH)+1) && day > today.get(Calendar.DAY_OF_MONTH)) {
         age--;
     }

     return age;
 }
