Ejemplo 2: como calcular la edad en la entrada de dob en java

importjava.text.ParseException;importjava.text.SimpleDateFormat;importjava.util.Calendar;importjava.util.Date;publicclassAgeCalculatorprivatestaticAgecalculateAge(Date birthDate)int years =0;int months =0;int days =0;//create calendar object for birth dayCalendar birthDay =Calendar.getInstance();
      birthDay.setTimeInMillis(birthDate.getTime());//create calendar object for current daylong currentTime =System.currentTimeMillis();Calendar now =Calendar.getInstance();
      now.setTimeInMillis(currentTime);//Get difference between years
      years = now.get(Calendar.YEAR)- birthDay.get(Calendar.YEAR);int currMonth = now.get(Calendar.MONTH)+1;int birthMonth = birthDay.get(Calendar.MONTH)+1;//Get difference between months
      months = currMonth - birthMonth;//if month difference is in negative then reduce years by one //and calculate the number of months.if(months <0)
         years--;
         months =12- birthMonth + currMonth;if(now.get(Calendar.DATE)< birthDay.get(Calendar.DATE))
            months--;elseif(months ==0&& now.get(Calendar.DATE)< birthDay.get(Calendar.DATE))
         years--;
