VB.NET Queue

In VB.NET, the Queue is used to store a collection of objects that follow FIFO (First In, First Out). Generally, the Queue class is provided by the VB .NET collection, which is useful for accessing elements from a collection of objects in the first-in-first-out style, which means the item inserted first in the queue will come out first from the queue. Furthermore, it uses Enqueue() and Dequeue() operation to insert and delete element from the collection of objects in Queue, where the Enqueue() operation is used to add elements at the end of the queue, and the Dequeue() operation is used to remove items starting from the queue.

The following is the pictorial representation of the Enqueue and Dequeue process in the VB.NET Queue.
