Scala Mutable SortedSet exists() method

  • Last Updated : 26 Mar, 2020

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 s1 = SortedSet(17, 7, 27, 37
          
        // Applying exists method 
        val result = s1.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 s1 = SortedSet(15, 2, 3, 45, 6
          
        // Applying exists method 
        val result = s1.exists(y => {y % 7 == 0}) 
          
        // Displays output 
        println(result) 
          
    
Output:
false
