【Java 数据结构及算法实战】系列 014：Java队列08——数组实现的双端队列ArrayDeque

ArrayDeque是基于数组实现的无界双端队列。ArrayDeque中的数组没有容量限制，它们能根据需要增长以支持使用。需要注意的是ArrayDeque不是线程安全的，因此在没有外部同步的情况下，它们不支持多线程并发访问。ArrayDeque用作栈时可能比Stack更快，用作队列时可能比Linke...

【Java数据结构及算法实战】系列012：Java队列06——数组实现的优先级阻塞队列PriorityBlockingQueue

PriorityBlockingQueue是基于数组实现的无界优先级阻塞队列。PriorityBlockingQueue与PriorityQueue类似，其中的元素按其自然顺序排序，或由队列构造时提供的比较器根据所使用的构造函数排序。优先级队列不允许空元素，依赖自然顺序的优先级队列也不允许插入不可比...

【Java数据结构及算法实战】系列011：数组实现的优先级队列PriorityQueue

PriorityQueue是基于数组实现的无界优先级队列。PriorityQueue中的元素按其自然顺序排序，或由队列构造时提供的比较器根据所使用的构造函数排序。优先级队列不允许空元素，依赖自然顺序的优先级队列也不允许插入不可比较的对象。PriorityQueue本质上就是一个最小堆存储结构数组，通...

【Java数据结构及算法实战】系列009：Java队列03——数组实现的阻塞队列ArrayBlockingQueue

顾名思义，ArrayBlockingQueue是基于数组实现的有界阻塞队列。该队列对元素进行FIFO排序。队列的首元素是在该队列中驻留时间最长的元素。队列的尾部是在该队列中停留时间最短的元素。新的元素被插入到队列的尾部，队列检索操作获取队列头部的元素。ArrayBlockingQueue是一个经典的...
