Scala program to create a queue using Queue collection class

Here, we are going to learn how to create a queue using Queue collection class in Scala programming language?
Submitted by Nidhi, on June 13, 2021

Problem Solution:

Here, we will create two queues using the Queue collection class. Then we will print both created queues 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 an item in the queue from different ends of the queue.

Program/Source Code:

The source code to create a queue using the Queue collection class is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to create a queue using
// Queue collection class

import scala.collection.immutable._

object Sample {
  // Main method
  def main(args: Array[String]) {
    var queue1 = Queue(10, 20, 30, 40, 50);
    var queue2 = Queue("Hello", "Hi", "Bye");

    println(queue1)
    println(queue2)
  }
}

Output:

Queue(10, 20, 30, 40, 50)
Queue(Hello, Hi, Bye)

Explanation:

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

import scala.collection.immutable._

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 two queues queue1 and queue2 using Queue collection class. The queue1 contains integer elements and queue2 contains string elements. After that, we printed the created queues on the console screen.
