Continue reading stdin until "END" in Scala?

How do I continue reading stdin until "END" string reached, in Scala?

Here's what I've tried:

val text = Iterator.continually(Console.readLine).takeWhile(_ != "END").toString
Solution

  • You should use mkString instead of toString here:

    val text = Iterator.
    continually(Console.readLine).
    takeWhile(_ != "END").
    mkString("\n")

    mkString on collection aggregates all elements in a string using optional separator.
