Scala Mutable SortedSet exists() method
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 program of exists() // method import scala.collection.mutable.SortedSet // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating a list val s 1 = SortedSet( 17 , 7 , 27 , 37 ) // Applying exists method val result = s 1 .exists(y => {y % 3 == 0 }) // Displays output println(result) } } |
Output:
true
Example #2:
// 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 s 1 = SortedSet( 15 , 2 , 3 , 45 , 6 ) // Applying exists method val result = s 1 .exists(y => {y % 7 == 0 }) // Displays output println(result) } } |
Output:
false
