Kotlin 의 constructor 와 init 중에 누가 먼저 호출될까?

Copy 
1class Person(private val name: String) { //primary constructor
2    private var age: Int = 0
3    set(value) {
4        println("property called")
5        field = value
6    }
7    private lateinit var address: String
8    private lateinit var company: String
9
10    constructor (name: String, age: Int, address: String) : this(name) { //secondary constructor
11        println("constructor 1 called")
12        this.age = age
13        this.address = address
14    }
15
16    constructor (name: String, age: Int, address: String, company: String) : this(name) { //secondary constructor
17        println("constructor 2 called")
18        this.age = age
19        this.address = address
20        this.company = company
21    }
22
23    init {
24        println("init called")
25        if (!::address.isInitialized)
26            this.address = "unknown address"
27        if (!::company.isInitialized)
28            this.company = "unknown company"
29
30    }
31}

Copy 
1val reno = Person("Reno", 31, "Seoul", "KM")
