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.
PriorityBlockingQueue优先级队列,线程安全(添加、读取都进行了加锁)、无界、读阻塞的队列,底层采用的堆结构实现(二叉树),默认是小根堆,最小的或者最大的元素会一直置顶,每次获取都取最顶端的数据 队列创建 小根堆 PriorityBlockingQueue<Integer>concurrentLinkedQueue=newPriorityBlockingQueue<Integer>(); ...
