scala> def isStringArray(x: Any) = x match {

case a: Array[String] => “yes”

case _ => “no” } isStringArray: (x: Any)java.lang.String

scala> val as = Array(“abc”) as: Array[java.lang.String] = Array(abc) scala> isStringArray(as) res21: java.lang.String = yes

scala> val ai = Array(1, 2, 3) ai: Array[Int] = Array(1, 2, 3) scala> isStringArray(ai) res22: java.lang.String = no
