Using Scala Separator and iterate the values

Question

Hi am new in scala basic

i have a doubt

This is about separator in scala

Here the string separated by comma and the string will separated and print it down

i don'nt know this code is possible for that

object SeparatorDemo {
  def main(args: Array[String]) {
    var stmt:String=("a,number,of,words")
    var p=stmt.split(",")
    var x=p.length
    for(i <-0 to x){
      println(p)
     }
   }
}

output:

[Ljava.lang.String;@142c842c
[Ljava.lang.String;@142c842c
[Ljava.lang.String;@142c842c
[Ljava.lang.String;@142c842c
[Ljava.lang.String;@142c842c

with regards Mila

Not sure who and why was it negative voted. Anyone who is new to scala is welcome to ask questions. If question was not having correct details instead of marking -1 better Edit it and mention in comment :-) — prash

You're printing out the array p at each iteration. You want to print out the contents of the array that contains the strings. I simplified it to this version.

object SeparatorDemo {
  def main(args: Array[String]) {
    var stmt:String=("a,number,of,words")
    var words=stmt.split(",")
    for(word <- words){
      println(word)
    }
  }
}

Even more concise is to chain the splitting and the iteration into one statement: stmt.split(",").foreach(println(_))

Either way gives this output:

scala> SeparatorDemo.main(Array())
a
number
of
words
