Scala - Print Queue's Last Element

In this program, we will create a queue using the Queue collection class and get the last item of the queue using the last() method and print 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.

Scala code to print the last item of the queue

The source code to print the last item of the queue is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to print the last item of the queue

import scala.collection.mutable._

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

    var result = queue.last;

    println("Last item of queue is: " + result);
  }
}

Output

Last item of queue is: 50

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 got the last item of the queue using the last() method and printed the result on the console screen.
