Basic Data Structure Interview Questions for Freshers.('Dequeue : ' + queueArrayįor (int i = 0 i < queueArray. We will do the Queue implementation in Java using Java Arrays. A Queue is a First-In-First-Out Data Structure.īefore we dig into the Queue implementation, let's first understand some basic terminology which will help us understand Queue's better.Īs you can see in the image above, Inserting a new element is done at the end of the queue and it is called as enqueue, while removing the element is done at the front of the queue and it is referred as dequeue. Thus the first one to enter the queue is the first one to come out from the queue and unlike stack, queue is open at both ends. The person who joins the queue first gets served first. Through this post we will learn the implementation of Queue Data- Structure in Java.
