Scala SortedMap keys() method with example Last Updated : 03 Nov, 2019 Comments Improve Suggest changes Like Article Like Report The keys() method is utilized to give an iterator over all the keys of the SortedMap. Method Definition: def keys: Iterable[A] Return Type: It returns an iterator over all the keys of the SortedMap. Example #1: Scala // Scala program of keys() // method import scala.collection.immutable.SortedMap // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating SortedMap val m1 = SortedMap("geeks" -> 5, "for" -> 3, "cs" -> 2) // Applying keys method val result = m1.keys // Displays output println(result) } } Output: Set(cs, for, geeks) Example #2: Scala // Scala program of keys() // method import scala.collection.immutable.SortedMap // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating SortedMap val m1 = SortedMap("geeks" -> 5, "for" -> 3, "geeks" -> 5) // Applying keys method val result = m1.keys // Displays output println(result) } } Output: Set(for, geeks) So, the identical keys are taken only once.
