zipWithIndex – Clear ur Doubt

Hey there! Welcome to ClearUrDoubt.com. In this post, we will look at a Scala program to convert an Array into an instance of Map. Let’s look at the program:

object ArrayToMap extends App {

  val ints = Array(1, 2, 3, 4)
  val strings = Array("ONE", "TWO", "THREE", "FOUR")

  //Convert above ints and strings arrays into a Map
  val mapIntToStrings = (ints zip strings).toMap
  println("Int to String Map = " + mapIntToStrings.mkString(", "))

  //Convert above ints and corresponding indices into a Map
  val mapIntsToIndices = (ints zipWithIndex).toMap
  println("Int to Index Map = " + mapIntsToIndices.mkString(", "))
}

object ArrayToMap extends App {

val ints = Array(1, 2, 3, 4)

val strings = Array("ONE", "TWO", "THREE", "FOUR")

//Convert above ints and strings arrays into a Map

val mapIntToStrings = (ints zip strings).toMap

println("Int to String Map = " + mapIntToStrings.mkString(", "))

//Convert above ints and corresponding indices into a Map

val mapIntsToIndices = (ints zipWithIndex).toMap

println("Int to Index Map = " + mapIntsToIndices.mkString(", "))

}
