init function for initializing List in Kotlin

I am trying to give init function some extra handling using the if else conditions:

val allDates = List<String>(daysInMonth) { "0$it" if(it/10 == 0) else it.toString() })

This is not a valid syntax for the init function and there seems to be very little information on this out there. Any suggestions on how to do this?

if you want declare first array allDates

the init for allDates like this

val daysInMonth = 30
    val allDates = arrayListOf<String>()
    for(i in 1..daysInMonth){
        if(i/10 == 0){
            allDates.add("0$i")
        }else{
            allDates.add("$i")
        }
    }

it looks like your if statement is wrongly formated, try this

val allDates = List<String>(daysInMonth) {  if(it/10 == 0) "0$it" else it.toString() }
