Scala immutable TreeSet find() method

In Scala immutable TreeSet class, the find() method is utilised to return an element that satisfies a given predicate in the TreeSet.

Method Definition: def find(p: (A) => Boolean): Option[A]

Return Type: It returns the first element that satisfies a given predicate if present or else it returns None.

Example #1:

// Scala program of find()
// method

// Import TreeSet
import scala.collection.immutable._

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {

        // Creating TreeSet
        val t1 = TreeSet(2, 4, 6, 7, 8, 9)

        // Print the TreeSet
        println(t1)

        // Applying find() method
        val result = t1.find(x => {x % 7 == 0})

        // Displays output
        println("Element divisible by 7: " + result)

    }
}

Output:

TreeSet(2, 4, 6, 7, 8, 9)
Element divisible by 7: Some(7)

Example #2:

// Scala program of find()
// method

// Import TreeSet
import scala.collection.immutable._

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {

        // Creating TreeSet
        val t1 = TreeSet(2, 4, 6, 7, 8, 9)

        // Print the TreeSet
        println(t1)

        // Applying find() method
        val result = t1.find(x => {x % 10 == 0})

        // Displays output
        println("Element divisible by 10: " + result)

    }
}

Output:

TreeSet(2, 4, 6, 7, 8, 9)
Element divisible by 10: None
