The map() method is utilized to build a new queue by applying a function to all elements of this queue.
Method Definition: def map[B](f: (A) => B): Queue[B] Return Type: It returns a new queue containing all the elements after applying the given function.
Example #1:
// Scala program of map() 
// method 
  
// Import Queue  
import scala.collection.mutable._
  
// Creating object 
object GfG 
  
    // Main method 
    def main(args:Array[String]) 
    
      
        // Creating a queue 
        val q1 = Queue(1, 3, 2, 7, 6, 5
          
        // Print the queue
        println(q1)
          
        // Applying map method 
        val result = q1.map(x => x*x)
          
        // Display output
        print("New queue after squaring all elements: " + result)
          
    

                    
Output:
Queue(1, 3, 2, 7, 6, 5)
New queue after squaring all elements: Queue(1, 9, 4, 49, 36, 25)
Example #2:
// Scala program of map() 
// method 
  
// Import Queue  
import scala.collection.mutable._
  
// Creating object 
object GfG 
  
    // Main method 
    def main(args:Array[String]) 
    
      
        // Creating a queue 
        val q1 = Queue(1, 3, 2, 7, 6, 5
          
        // Print the queue
        println(q1)
          
        // Applying map method 
        val result = q1.map(x => x/2)
          
        // Display output
        print("New queue after dividing all elements by 2: " + result)
          
    

                    
Output:
Queue(1, 3, 2, 7, 6, 5)
New queue after dividing all elements by 2: Queue(0, 1, 1, 3, 3, 2)
