Scala split function error

Question

Can you please correct my code.I am trying to print x22 by spliting x11.

object ScalaString {

  def main(args: Array[String]): Unit = {
    var x =" Hello world"
    x.filter(_!='l').foreach(println)
    //for(c <- x) println(c)
   println(x.stripPrefix(" ").drop(2).take(2).capitalize)
    **var x11=" hello|world|india"
    var x22=( x11.split("|").map(_.trim()))
    println(x22.toString())**

  }

}

output:
w
o
r
d
Ll
**[Ljava.lang.String;@56431753**

That's what the toString of an Array looks like. Try x22.mkString instead.

Hello Boss,Thats worked perfectly. Please let me know what the difference.. Why it was showing the memory address.

The difference is... it's a different function. Array functions in general are optimized for performance rather than anything else; in general e.g. Vector is similar but more user-friendly, and has a toString that returns something more sensible. split returns an Array because that's the java.lang.String API.
