Scala mutable SortedSet ++() method Last Updated : 22 Apr, 2020 Summarize Comments Improve Suggest changes Share Like Article Like Report In Scala mutable collection, ++() method is utilized to add elements of one SortedSet to another SortedSet. Method Definition: def ++(elems: A): SortedSet[A] Return Type: It returns a new TreeSet containing elements of both the SortedSets. Example #1: Scala // Scala program of ++() method import scala.collection.mutable.SortedSet // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating a SortedSet val s1 = SortedSet(1, 3, 5) val s2 = SortedSet(2, 4, 6) // Applying ++() method val result = s1 ++ s2 // Display output print(result) } } Output: TreeSet(1, 2, 3, 4, 5, 6) Example #2: Scala // Scala program of ++() method import scala.collection.mutable.SortedSet // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating a SortedSet val s1 = SortedSet(41, 12, 23, 43, 1, 72) val s2 = SortedSet(1, 100, 5, 12, 23) // Applying ++() method val result = s1 ++ s2 // Display output print(result) } } Output: TreeSet(1, 5, 12, 23, 41, 43, 72, 100) Comment More infoAdvertise with us Next Article Scala Mutable SortedSet -() method S Shivam_k Follow Improve Article Tags : Scala Scala Mutable-collections Scala mutable-sortedset Similar Reads Scala Mutable SortedSet +() method In Scala mutable collections, +() method is utilized to create a new SortedSet with an additional element unless the element is already present.
