基于数组(Array) 基于链表(Linked List) 基于环形缓存器(Circular Buffer) 基于堆(Heap) 这里我们只讨论基于最基本的数组来实现。 1. 基本实现 我们可以基于数组来实现一个基本的队列结构,这个队列支持以下几种接口: count:元素个数 isEmpty:是否为空 front:第一个元素 enqueue:加入元素到队列 dequeue:从队列中移...
In JDK 7,TransferQueueis a specializedBlockingQueuein which code that adds an element to the queue has the option of waiting (blocking) for code in another thread to retrieve the element.TransferQueuehas a single implementation: LinkedTransferQueue— an unboundedTransferQueuebased on linked nodes...

LinkedListis a doubly-linked list implementation of theQueueinterface in Java. It allows both FIFO and LIFO (Last-In-First-Out) operations, making it a versatile choice. Here’s an example of using aLinkedListas a queue: Queue<String>queue=newLinkedList<>();queue.offer("item1");queue.offe...
Now that we’ve got that we can make a first cut at our queue implementation. Let’s say that a queue is backed by a stack such that every time we need to get at the “dequeue end”, we’ll just reverse the stack: sealed class Queue<T> : IQueue<T> { private static read...
Provided is a lock-free message queue implementation method based on a reversal single linked list. The lock-free message queue implementation method based on the reversal single linked list is used for a 2-thread server framework and comprises a) a data structure of a lock-free message queue...
