Getting Queue Element From Head For Inspecting

Using Java Queue via LinkedList

The Queue operates on ‘First In First Out (FIFO)’ principle. This means an element added first to the Queue removed first from the queue. For example, in a railway ticket counter the person who enters the queue first will be served first and removed from the queue. Each new person coming to buy the ticket will stand in the tail end of the queue. The same Queue will work in Java. In simple words, elements are added to the tail end of the Queue and removed from the head of the Queue.

In this example, we will see how to use Java Linked as a Queue.
