Scala Stack find() method with example

In Scala Stack class, the find() method is utilized to return an element that satisfies a given predicate in the stack.

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 Stack
import scala.collection.mutable._

// Creating object
object GfG
{

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

        // Creating stack
        val s1 = Stack(1, 3, 2, 7, 6, 5)

        // Print the stack
        println(s1)

        // Applying find method
        val result = s1.find(x => {x % 7 == 0})

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

Output:

Stack(1, 3, 2, 7, 6, 5)
Element divisible by 7: Some(7)

Example #2:

// Scala program of find()
// method

// Import Stack
import scala.collection.mutable._

// Creating object
object GfG
{

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

        // Creating stack
        val s1 = Stack(1, 3, 2, 7, 6, 5)

        // Print the stack
        println(s1)

        // Applying find method
        val result = s1.find(x => {x % 10 == 0})

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

Output:

Stack(1, 3, 2, 7, 6, 5)
Element divisible by 10: None
