Java Queue

The Java Queue interface represents a data structure where you add elements to the end of the queue, and remove them from the beginning of a queue. This is similar to how a queue in a supermarket works. Customers enqueue themselves at the end of the queue, and are served one by one from the beginning of the queue.

Great tutorial! I follow all tutorials in textual and video versions. I learn Java for my college and this tutorials are extremely helpful.

Very good. Explaining the difference between the methods that throw exceptions vs. ones that return a special value is important. Other channels omit that and then have two dozen confused people asking questions and making wrong guesses in the comments.

Amazing explanation, so happy I found your channel.
As a suggestion, please create a playlist of all the java collections, they are very confusing to master.

YouTube should not be a ground to showcase one's expertise, but it should be a platform to explain things in details. For example, we don't know about anything Customer class in this video and just be like a parrot. So many dislikes to this video.
