How to use `slice` In Scala

The slice method provides a more flexible approach for extracting a sub-array from within the original array. It takes two integer arguments:

  • The starting index (inclusive) of the sub-array to extract.
  • The ending index (exclusive) of the sub-array to extract.

Example:

Scala
object Main {
    def main(args: Array[String]) {
        
      val colors = Array("red", "green", "blue", "yellow", "purple")
      val subColors = colors.slice(1, 4) // Extract elements from index 1 (inclusive) to 4 (exclusive)

      println(subColors.mkString(", "))  // Output: green, blue, yellow
    }
}

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.
