Queue in Java Programming

What is Queue in Java

A Queue in Java is a data structure in which we can add elements only at one end, called the rear of the queue, and remove elements only from the other end, called the front of the queue. It follows the First In, First Out (FIFO) principle, meaning the first element added to the queue is the first one to be removed.

We can see the example of a queue in our daily life as the queue of people.

In the above image, we can see that new people can join the queue from the rear end, and when the work is over, the people at the front will leave first.
