Implement Queue using Linked List in java

If you want to practice data structure and algorithm programs, you can go through 100+ java coding interview questions.

In this post , we will see how to implement Queue using Linked List in java.
Queue is abstract data type which demonstrates First in first out (FIFO) behaviour. We will implement same behaviour using Array.
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.
Please note that LinkedList implementation of Queue is dynamic in nature.
There are two most important operations of Queue:
enqueue : It is operation when we insert element into the queue.
dequeue : It is operation when we remove element from the queue. Read more at

When you run above program, you will get below output:
