Problem with this constructor chaining and virtual method invocation

open class Person( open var age: Int,  name: String) {
   init {
     
       println("My name is $name.")
       println("My age is $age")
   }
}

class MathTeacher( override var age :Int,  var name : String): Person(age,name) {

   fun teachMaths() {
       println("I teach in primary school $age")
   }
}

class Footballer(age: Int, name: String): Person(age, name) {
   fun playFootball() {
       println("I play for LA Galaxy.")
   }
}

fun main(args: Array<String>) {
   val t1 = MathTeacher(25, "Jack")
   t1.teachMaths()
println(t1.age)
   println()

   val f1 = Footballer(29, "Christiano")
   f1.playFootball()
}


So when I run this code the first thing called is the base class constructor, I get that , then it does assignment, I don’t understand why when I am printing the name and age I don’t get a null and zero value,

Why would you expect null and 0? The values you pass to the subclass constructors get passed to the superclass Person constructor and that's what gets printed.
