Kotlin, println with prompts and getting user input - visual-studio

Question

First Name
Last Name
Street Address
City
State - 2 digits in length
Zip - Integer 4 digits in length (minimum and maximum)
GPA (from 0.0 to 4.0)
Major - String
Teacher Class - overrides the student class
The main class should
Instantiate the student class and prompt the user to enter each of these properties
Print out the data from the instantiated class.
Instantiate the teacher class.
Print out the data from the instantiated class.
I'm new to Kotlin but this is what I have so far.
How do I prompt the user for each data point, get their input for each, and then print the user input out as a whole once all info is entered
Ideal output
First Name: ...
Last Name: ...
Then once all info is entered it prints the entirety of the info entered by user with prompts.
open class Student(first: String, last: String, street: String, city: String, state: String, zip: Int, gpa: Int, major: String)
{
var firstName : String?= first
var lastName : String?= last
var streetAddress: Int?= street
var city: String?= city
var state : String?=state
var zip:Int?=zip
var gpa: Int?=gpa
var major: String?=major
}
class Teacher (first: String):Student (first)
fun main() {
