Java集合队列之ArrayQueue小结 简述 Resizable-array implementation of the Deque interface. Array deques have no capacity restrictions; they grow as necessary to support usage. They are not thread-safe; in the absence of external synchronization, they do not support concurrent access by multiple threads...
* The array in which the elements of the deque are stored. * The capacity of the deque is the length of this array, which is * always a power of two. The array is never allowed to become * full, except transiently within an addX method where it is ...
Java并发基础：ArrayBlockingQueue全面解析！ - 程序员古德内容摘要ArrayBlockingQueue类是一个高效、线程安全的队列实现，它基于数组，提供了快速的元素访问，并支持多线程间的同步操作，作为有界队列，它能有效防止内存溢出，并通过阻塞机制平衡生产者和消费者的速度差异，它还提供了公平性和非公平性策略，满足不同场景下...

LinkedBlockingDeque:一个由链表结构组成的双向阻塞队列。 对了,小编说说我对有界和无界的理解,我也不清楚对还是不对,不对的话麻烦你评论告诉小编,灰常感谢! 从实现方面讲: 有界: 指的是实现里头持有的资源(数组)是有大小的,即容量是有限的 无界: 指的是持有一个无界的链表 ...
