Scala Mutable SortedMap filter() method with example Last Updated : 04 May, 2020 Comments Improve Suggest changes Like Article Like Report The filter() method is utilized to select all elements of the SortedMap which satisfies a stated predicate. Method Definition: def filter(p: ((A, B))=> Boolean): SortedMap[A, B] Return Type: It returns a new SortedMap consisting all the elements of the SortedMap which satisfies the given predicate. Example #1: Scala // Scala program of filter() // method import scala.collection.SortedMap // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating SortedMap val m1 = SortedMap("geeks" -> 5, "for" -> 3) // Applying filter method val result = m1.filter(x => x._1 == "geeks" && x._2 == 5) // Displays output println(result) } } Output: Map(geeks -> 5) Example #2: Scala // Scala program of filter() // method import scala.collection.SortedMap // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating SortedMap val m1 = SortedMap("geeks" -> 5, "for" -> 3) // Applying filter method val result = m1.filter(x => x._1 == "for" && x._2 == 5) // Displays output println(result) } } Output: Map() Here, an empty SortedMap is returned as none of the elements satisfy the stated predicate.
