Taking inputs

2

This question seems to target Java in general, not a Kotlin specific problem. At least Scanner works for me without System.in. 

import java.util.Locale
import java.util.Scanner



fun main(args: Array<String>) {

  Locale.setDefault(Locale.ENGLISH)

  println(Scanner(“42”).nextInt())

  println(Scanner(“42”).nextDouble())

  println(Scanner(“42.3”).nextDouble())

  println(Scanner(“true”).nextBoolean())

}
