pattern matchの練習。Regexpでpattern matchして数値文字列を変換する

gistfile1.scala

val r  = """^(\d+)$""".r
var hoge = "123456789" match {
  case r(n)  => n.toInt
  case _ => println("Do not matched")
}

val huga = Array("9876") match {
  case n if n.size ==1 => 
    n(0) match {
      case re(t) => t.toInt
      case _ => 8080
    }
  case _ => 8080
}
