Scala SortedSet exists() method with example

Last Updated : 03 Nov, 2019

The 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

// Scala program of exists() 
// method 
import scala.collection.immutable.SortedSet 

// Creating object 
object GfG 
{ 

    // Main method 
    def main(args:Array[String]) 
    { 
        // Creating a list 
        val s1 = SortedSet(1, 2, 3, 4, 5) 
        
        // Applying exists method 
        val result = s1.exists(y => {y % 3 == 0}) 
        
        // Displays output 
        println(result) 
        
    } 
}

Output:

true

Example #2:

Scala

// Scala program of exists() 
// method 
import scala.collection.immutable.SortedSet 

// Creating object 
object GfG 
{ 

    // Main method 
    def main(args:Array[String]) 
    { 
        // Creating a list 
        val s1 = SortedSet(1, 2, 3, 4, 5) 
        
        // Applying exists method 
        val result = s1.exists(y => {y % 7 == 0}) 
        
        // Displays output 
        println(result) 
        
    } 
}

Output:

false
