// 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)
