LinkedBlockingQueue 多用于任务队列(单线程发布任务,任务满了就停止等待阻塞,当任务被完成消费少了又开始负载 发布任务) ConcurrentLinkedQueue 多用于消息队列(多个线程发送消息,先随便发来,不计并发的-cas特点) 单生产者,单消费者 用 LinkedBlockingqueue 多生产者,单消费者 用 LinkedBlockingqueue 单生产者 ,多消...

LinkedList与ArrayList一样实现List接口,只是ArrayList是List接口的大小可变数组的实现,LinkedList是List接口链表的实现。基于链表实现的方式使得LinkedList在插入和删除时更优于ArrayList,而随机访问则比ArrayList逊色些。 LinkedList实现所有可选的列表操作,并允许所有的元素包括null。除了实现 List 接口外,LinkedList 类还为在...
Linked list (LinkedList<T>) 当元素需要能够在列表的两端添加时。否则使用 List<T>。 Resizable array list (List<T>) 当元素的数量不是固定的,并且需要使用下标时。 Stack (Stack<T>) 当需要实现 LIFO(Last In First Out)时。 Queue (Queue<T>) ...
Some queues panic. Personally I approve of this if it's done right (seeRANT.md), butnotusing panic is a better fit with the rest of the library/language. Many queues use linked lists with one element per node, leading to the same performance problemscontainer/listhas. ...

An optionally-boundedblocking queuebased on linked nodes. This queue orders elements FIFO (first-in-first-out). Theheadof the queue is that element that has been on the queue the longest time. Thetailof the queue is that element that has been on the queue the shortest time. New elements...
A priorityQueue can be configured to use min-heap or max-heap using method WithMinHeap. If the parameter is true, then it's a min-heap, which is the default option as well; otherwise, it's a max-heap. WithMinHeap(isMinHeap bool) Interface LinkedMap LinkedMap is based on a map and...
