SCALA: change the separator in Array

Question

I have an Array like this.

scala> var x=Array("a","x,y","b")
x: Array[String] = Array(a, x,y, b)

How do I change the separator comma in array to a :. And finally convert it to string like this.

String = "a:x,y:b"

My aim is to change the comma(separators only) to other separator(say,:), so that i can ignore the comma inside second element i.e, x,y. and later split the string using : as a delimiter

Your question is unclear, but I'll take a shot.

To go from:

val x = Array("a","x,y","b")

to

"a:x,y:b"

You can use mkString:

x.mkString(":")
