In Scala ListSet, exists() method is utilized to check if the given predicate satisfies the elements of the listSet 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 listset else it returns false.

Example 1:




// Scala program of exists() 
// method 
import scala.collection.immutable._
// Creating object 
object GfG 
  
    // Main method 
    def main(args:Array[String]) 
    
      
        // Creating Listset
        val m1 = ListSet(1, 2, 3, 4, 5, 7
          
        // Applying exists method 
        val result = m1.exists(_==9
          
        // Displays output 
        println(result) 
      
    


Output:

false

Example 2:




// Scala program of exists() 
// method 
import scala.collection.immutable._
// Creating object 
object GfG 
  
    // Main method 
    def main(args:Array[String]) 
    
      
        // Creating listset 
        val m1 = ListSet(1, 2, 3, 4, 5, 7
          
        // Applying exists method 
        val result = m1.exists(_>9
          
        // Displays output 
        println(result)
