Scala - Find Largest Element from the Queue

Here, we will create a queue using the Queue collection class and get the largest item from the queue using the max() 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 find the largest element from the queue

The source code to find the largest element from the queue is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to find the largest element from queue

import scala.collection.mutable._

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

    var max = queue.max;

    println("Largest element is: " + max);
  }
}

Output

Largest element is: 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 got the largest item from the queue using the max() method and printed the result on the console screen.
