A Stack is a linear data structure that follows the LIFO (Last-In-First-Out) principle. Stack has one end, whereas the Queue has two ends (front and rear). It contains only one pointer top pointer pointing to the topmost element of the stack. Whenever an element is added in the stack...
Queue Data Structure A queue is a useful data structure in programming. It is similar to the ticket queue outside a cinema hall, where the first person entering the queue is the first person who gets the ticket. Queue follows the First In First Out (FIFO) rule - the item that goes in...

Priority queue is a special type of queue, it store item into queue with associated priority. So that it does not support FIFO( First In First Out) structure.It supports the following three operations: InsertWithPriority: Insert an item to the queue with associated priority. GetNext:...

However, the functionality of queue data structure is best provided by ArrayDeque. So, we mostly use ArrayDeque Class to create a Queue object if we require the functionalities of a queue only. A program to create a queue is shown below. Java import java.util.*; public class Main { pu...
