import scala.io.Source

object Test {

  def main(args: Array[String]) {

    matchTest("two")

  }

  def matchTest(x: Any) {

    println(x);

  }

}

object Test {

  def main(args: Array[String]) {

     var myList1 = Array(8.9, 7.9, 0.4, 1.5)

     // list iteration..

     for(x <- myList1) {
