Scala Mutable SortedSet exists() method Last Updated : 26 Mar, 2020 Comments Improve Suggest changes Like Article Like Report In Scala mutable collections, SortedSet exists() method is utilized to test whether a predicate holds for some of the elements of the SortedSet or not. Method Definition: def exists(p: (A) => Boolean): Boolean Return Type: It returns true if the stated predicate holds true for some elements of the SortedSet else it returns false. Example #1: Scala // Scala program of exists() // method import scala.collection.mutable.SortedSet // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating a list val s1 = SortedSet(17, 7, 27, 37) // Applying exists method val result = s1.exists(y => {y % 3 == 0}) // Displays output println(result) } } Output: true Example #2: Scala // Scala program of exists() // method import scala.collection.mutable.SortedSet // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating a list val s1 = SortedSet(15, 2, 3, 45, 6) // Applying exists method val result = s1.exists(y => {y % 7 == 0}) // Displays output println(result) } } Output: false Comment More infoAdvertise with us Next Article Scala Mutable SortedSet exists() method S Shivam_k Follow Improve Article Tags : Python Scala Scala Scala-Method Scala mutable-sortedset +1 More Practice Tags : python Similar Reads Scala Mutable SortedSet init() method In Scala mutable collections, SortedSet init() method is utilized to find all the elements of the SortedSet except the last one.
