I'm writing a simple app in vim + gradle:

class App {
  val listA = listOf(1, 8, 12, 17, 26, 31)
}

fun main(args: Array<String>) {
  val app = App()
  while (app.listA.hasNext()) {
    println(app.listA.next())
  }
}

But get this on

gradle run

Unresolved reference: hasNext
Unresolved reference: next

Have I forgot something? Something in Gradle?

yes… the rest of the question 😄

Sorry, I'll explain

Ah, you need to get an iterator first

Oops, my bad 🙂 Thanks

I don’t think you can. Just get a new one from the list

Thanks, I have not found a way to do it myself, but I was not sure that I know everything 🙂

what is your use case? Because sample above perfectly replaced with forEach

It was test-case to reveal how iterators work

I see
