Scala SortedMap exists() method with example Last Updated : 03 Nov, 2019 Comments Improve Suggest changes Like Article Like Report The exists() method is utilized to check if the given predicate satisfy the elements of the SortedMap or not. Method Definition: def exists(p: ((A, B)) => Boolean): Boolean Return Type: It returns true if the stated predicate holds true for some elements of the SortedMap else it returns false. Example #1: Scala // Scala program of exists() // 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) // Applying exists method val result = m1.exists(x => x._1 == "for" && x._2 == 3) // Displays output println(result) } } Output: true So, here the stated predicate is true for the second key-value pair so true is returned. Example #2: Scala // Scala program of exists() // 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) // Applying exists method val result = m1.exists(x => x._1 == "geeks" && x._2 == 3) // Displays output println(result) } } Output: false Comment More infoAdvertise with us Next Article Scala SortedMap exists() method with example G gopaldave Follow Improve Article Tags : Scala Scala Scala-Method Similar Reads Scala SortedMap get() method with example The get() method is utilized to give the value associated with the keys of the SortedMap.
