Scala Queue intersect() method with example

The intersect() method is utilized to return a new queue that consists of elements that are present in both the given queues.

Method Definition: def intersect[B >: A](that: collection.Seq[B]): Queue[A]

Return Type: It returns a new queue that consists of elements that are present in both the given queues.

Example #1:

// Scala program of intersect()
// method

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

// Creating object
object GfG
{

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

        // Creating queues
        val q1 = Queue(1, 3, 2, 7, 6, 5)

        val q2 = Queue(1, 13, 2, 17, 6, 15)

        // Print the queues
        println("Queue_1: " + q1)

        println("Queue_2: " + q2)

        // Applying intersect method
        val result = q1.intersect(q2)

        // Display output
        print("The elements in both the queues: ")

        result.foreach(x => print(x + " "))

    }
}

Output:

Queue_1: Queue(1, 3, 2, 7, 6, 5)
Queue_2: Queue(1, 13, 2, 17, 6, 15)
The elements in both the queues: 1 2 6

Example #2:

// Scala program of intersect()
// method

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

// Creating object
object GfG
{

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

        // Creating queues
        val q1 = Queue(1, 3, 2, 7, 6, 5)

        val q2 = Queue(11, 3, 12, 7, 16, 5)

        // Print the queues
        println("Queue_1: " + q1)

        println("Queue_2: " + q2)

        // Applying intersect method
        val result = q1.intersect(q2)

        // Display output
        print("The elements in both the queues: " + result)

    }
}

Output:

Queue_1: Queue(1, 3, 2, 7, 6, 5)
Queue_2: Queue(11, 3, 12, 7, 16, 5)
The elements in both the queues: Queue(3, 7, 5)
