Scala Queue Programs

A queue is a first-in-first-out (FIFO) data structure. In Scala programming language, there are both types of queues immutable and mutable. A mutable queue is a queue that can be updated or extended in place. An immutable queue is a queue that can never change.

The two most basic operations of Queue are,

  • Enqueue – Adding an element at the end of the queue.
  • Dequeue – Deleting an element from the beginning of the queue.

This section contains solved Scala Queue Programs, practice these Scala programs to learn the concept of Scala queues, these programs contain the solved code, outputs, and the detailed explanation of the statements, functions used in the Scala Queue Programs.

List of Scala Queue Programs

  1. Scala program to create a queue using Queue collection class
  2. Scala program to get the first item from the front-end in the queue
  3. Scala program to add an item in the queue using enqueue() method
  4. Scala program to delete an item from the queue using dequeue() method
  5. Scala program to check a queue is empty or not
  6. Scala program to remove all elements from the queue
  7. Scala program to compare two queues using equals() method
  8. Scala program to add items into the queue using the '+=()' method
  9. Scala program to add items into the queue using the '+:()' method
  10. Scala program to append a queue in another queue using the '++=()' method
  11. Scala program to check a queue contains a specified item
  12. Scala program to find the smallest element from the queue
  13. Scala program to find the largest element from the queue
  14. Scala program to calculate the sum of all queue elements
  15. Scala program to print the last item of the queue
  16. Scala program to get the first N item from the queue using take() method
