Java Programming for Complete Beginners - Java 16 - Step 20 - Queue Interface - Process Elements in Order

The video tutorial introduces the queue interface, explaining its purpose in organizing tasks for processing, such as in a to-do list. It highlights that queues extend the collection interface, supporting methods like add, offer, remove, poll, and peek. The tutorial also covers priority queues, which store elements in a natural order by default, but can be customized using comparator implementations. The video concludes with a transition to hands-on practice with queues.
