Answer 1

Now for kotlin Language:

import java.util.Calendar


fun main(args: Array) {


print(getAge(yyyy,mm,dd))

}

 fun getAge(year: Int, month: Int, day: Int): String {
    val dob = Calendar.getInstance()
    val today = Calendar.getInstance()

    dob.set(year, month, day)

    var age = today.get(Calendar.YEAR) - dob.get(Calendar.YEAR)

    if (today.get(Calendar.DAY_OF_YEAR) < dob.get(Calendar.DAY_OF_YEAR)) {
        age--
    }

    val ageInt = age + 1

    return ageInt.toString()
}
