Scala ListSet exists() method with example

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)

    }
}

Output:

false
