Splitting by Delimiter

If you want to split an array of strings based on a delimiter (a specific character or string), you can use the `split` method available on strings. However, since Scala arrays are not directly splittable, you need to convert the array to a string and then split it.

Example:

Scala
object Main {
    def main(args: Array[String]) {
       val words = Array("hello", "world", "how", "are", "you?")
       val splitWords = words.mkString(" ").split(" ")  // Convert to string, split on space

       println(splitWords.mkString(", "))  // Output: hello, world, how, are, you?

    }
}

How to split Array in Scala?

Arrays are a fundamental data structure in Scala, used to store collections of elements of the same type. Splitting an array involves dividing it into smaller sub-arrays based on specific criteria.

This article explores different methods for achieving this in Scala.
