Scala SortedMap copyToArray() method with example Last Updated : 03 Nov, 2019 Comments Improve Suggest changes Like Article Like Report The copyToArray() method is utilized in copying pair of keys of the SortedMap to an Array. Method Definition: def copyToArray(xs: Array[(A, B)]): Unit Return Type: It returns the keys of the SortedMap to an array. Example #1: Scala // Scala program of copyToArray() // method import scala.collection.immutable.SortedMap // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating a SortedMap val m1 = SortedMap("geeks" -> 5, "for" -> 3, "cs" -> 2) // Creating Array val x: Array[Any] = Array(0, 0, 0, 0, 0) // using 'copyToArray' method m1.copyToArray(x) // Displays keys copied in // the Array for(m2 <-x) println(m2) } } Output: (cs, 2) (for, 3) (geeks, 5) 0 0 So, here the keys are copied to the array. Example #2: Scala // Scala program of copyToArray() // method import scala.collection.immutable.SortedMap // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating a SortedMap val m1 = SortedMap("geeks" -> 5, "for" -> 3, "geeks" -> 5) // Creating Array val x: Array[Any] = Array(0, 0, 0, 0, 0) // using 'copyToArray' method m1.copyToArray(x) // Displays keys copied in // the Array for(m2 <-x) println(m2) } } Output: (for, 3) (geeks, 5) 0 0 0 Here, the identical keys are removed.
