Although java provides implementation for all abstract data types such as Stack, Queue and LinkedList but it is always good idea to understand basic data structures and implement them yourself. This Stack data structure is to store the integer values. Queue represents a data structure designed to have elements inserted at the end of the queue, and elements removed from the beginning of the queue. To implement a queue using array, create an array arr of size n and take two variables front and rear both of which will be initialized to 0 which means the queue is currently empty.
