In a queue, the first-in-first-out rule is implemented whereas, in a priority queue, the values are removed on the basis of priority. The element with the highest priority is removed first. Implementation of Priority Queue Priority queue can be implemented using an array, a linked list, a...
If you might remember the first person to enter the queue is the first to get out too once his/her job is done. Such a kind of setup of “first in first out” is also popularly abbreviated asFIFO. So with that, we have established that a queue follows a FIFO. A Queue in Java is...

Java PriorityQueue is an unbounded Queue implementation that processes the items based on priorities. Custom ordering can be enforced with a Comparator.

Java高并发系列之PriorityBlockingQueue源码解析 上一篇文章《Java高并发系列之DelayQueue源码解析》中元素具有过期时间,其中元素需要实现Delay接口,而Delay接口实现Comparable接口。这是因为DelayQueue内部使用了一个PriorityQueue作为优先队列,而优先队列需要元素的可比较性。 本文介绍PriorityBlockingQueue也是一种优先级队列,其基于...
