Here, we will create a queue using the Queue collection class and then we add an item into the queue using the "+=()" method. After that, we will print the updated queue 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 add items into the queue using the "+=()" method is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to add items into queue using
// the "+=()" method

import scala.collection.mutable._

object Sample {
  // Main method
  def main(args: Array[String]) {
    var queue = Queue(10, 20, 30, 40, 50);

    println("Queue elements:");
    queue.foreach((ele: Int) => print(ele + " "));
    println();

    //Add element into queue.
    queue += 60;

    println("Queue elements:");
    queue.foreach((ele: Int) => print(ele + " "));
    println();
  }
}

Output:

Queue elements:
10 20 30 40 50 
Queue elements:
10 20 30 40 50 60

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 item 60 into the queue using the "+=()" method and printed the updated queue on the console screen.
