大顶堆MaxHeap(原理与Java实现) 1. 为什么要引入堆? 1.1 堆的应用场景 有时候我们面临一种实际应用场景需要根据任务的重要程度而划分优先级,对优先级高的任务提供优先服务。 优先级队列(Priority Queue):取出元素的顺序是依据优先级大小,而不是元素进入队列的先后顺序。 优先级队列实现要求:维护这样一种结构,取出数...

每个插入操作必须等到另一个线程调用移除操作,否则插入操作一直处于阻塞状态,吞吐量通常要高于LinkedBlockingQueue,静态工厂方法Executors.newCachedThreadPool使用了这个队列。 4、PriorityBlockingQueue 一个具有优先级的无限阻塞队列。

堆的概念优先队列(priority queue)是一种特殊的队列,取出元素的顺序是按照元素的优先权(关键字)大小,而不是进入队列的顺序,堆就是一种优先队列的实现。堆一般是由数组实现的,逻辑上堆可以被看做一个完全二叉树(除底层元素外是完全充满的,且底层元素是从左到右排列的)。堆分为最大堆和最小堆,最大堆是指每个...
