Here, we will create a queue using the Queue collection class and then we will apply some logic to queue elements. After that, we printed the result on the console screen.

The Queue is a linear data structure, It follows the First In First Out (FIFO) property. We can insert and remove the item in the queue from different ends of the queue.

Program/Source Code:

The source code to demonstrate the map() method of the Queue class is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to demonstrate the
// map() method of Queue class

import scala.collection.mutable._

object Sample {
  // Main method
  def main(args: Array[String]) {
    var queue = Queue(60, 25, 23, 40, 50);

    var result = queue.map(v => v + 2);

    println(result);
  }
}

Output:

Queue(62, 27, 25, 42, 52)

Explanation:

Here, we used an object-oriented approach to create the program. And, we imported Collection classes using the below statement,

import scala.collection.mutable._

And, we also created a singleton object Sample and defined the main() function. The main() function is the entry point for the program.

In the main() function, we created a queue queue using the Queue collection class. Then we added 2 in each item of the queue using the map() method and printed the result on the console screen.
