A modern programming language that makes developers happier.

I'm writing a simple app in vim + gradle:
```
class App {
  val listA = listOf(1, 8, 12, 17, 26, 31)
}

fun main(args: Array&lt;String&gt;) {
  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?

In saying that, I’d use forEach rather:
`app.listA.forEach { println(it) }`

Oops, my bad :slightly_smiling_face: Thanks

One more question: how to reset iterator to the beginning?

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 :slightly_smiling_face:

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

It was test-case to reveal how iterators work
