Scala SortedSet exists() method with example

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 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 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
