It will throw an unchecked exception if you try to delete an element from an empty queue. Public class Main Īs you can see in the above code example, we used the remove() method in order to delete an item from the queue. Import // Class Which implements queue list etc. The following code example shows how one can create the object of the queue in Java. In Java, the queue is regarded as an interface that is implemented by a linked list. Now that you have a concrete understanding of the queue, let’s take a look at the implementation of the queue in Java. Take a look at the picture down below.Īs you can see, addition (enqueue) in the queue will always be from the back, and removal (dequeue) will always be from the front. So, when we say enqueue and dequeue in programming, we mean adding and removing an item, respectively. Whoever comes in first gets served first and goes out. A real-world example would be the line of people (queue) you see outside a bank. The one-way order is FIFO (first in, first out). Queue in terms of programming is a linear structure with a one-way order through which this datatype performs. What is it actually? The real-world example and much more. Before we get into the concepts of enqueue and dequeue in Java, let’s build up a basic understanding of the whole concept of Queue.
