Java Queue Explained: FIFO Guide

In Java, a Queue is a data structure that follows the First-In-First-Out (FIFO) principle and is used to store a series of elements. Queues are commonly used to add elements to a collection and retrieve and process them in the order they were added. In Java, Queue is an interface that extends the Collection interface and defines methods for operating on queues, such as adding elements to the end of the queue and removing and retrieving elements from the front. Java provides various classes that implement the Queue interface, such as LinkedList and PriorityQueue. Queues are typically used for tasks that need to be processed in the order they were added, such as task scheduling and message queues.
