Scala SortedMap exists() method with example
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 program of exists() // method import scala.collection.immutable.SortedMap // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating SortedMap val m 1 = SortedMap( "geeks" - > 5 , "for" - > 3 ) // Applying exists method val result = m 1 .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 program of exists() // method import scala.collection.immutable.SortedMap // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating SortedMap val m 1 = SortedMap( "geeks" - > 5 , "for" - > 3 ) // Applying exists method val result = m 1 .exists(x => x. _ 1 == "geeks" && x. _ 2 == 3 ) // Displays output println(result) } } |
Output:
false
