Scala Mutable SortedMap exists() method with example

Last Updated : 04 May, 2020

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.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.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
