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.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.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
