Code explanation to implementation of priority queue using linked list In the Code below there are four parts. First three function to implement three different operations like Insert a node, delete a node and display the list. The Fourth part is the main function, in that a do while loop i...
The method disclosed reduces the overall memory requirements for the design and implementation of queue systems with multiple queues sharing a common pool of memory.Patrick BaileyHeng Liao
插入元素是追加到尾上。提取一个元素是从头提取。当多个线程共享访问一个公共 collection 时,ConcurrentLinkedQueue 是一个恰当的选择。该队列不允许null元素。 This implementation employs an efficient "wait-free" algorithm based on one described in Simple, Fast, and Practical Non-Blocking and Blocking Concurre...

Implementation Note: TheSpliteratorimplementstrySplitto permit limited parallelism. Returns: aSpliteratorover the elements in this queue Since: 1.8 put public void put(Ee) Inserts the specified element at the tail of this queue. As the queue is unbounded, this method will never block. ...

Removes all of the elements from this queue. The queue will be empty after this call returns. This implementation repeatedly invokes poll until it returns null. Specified by: clear in interface Collection<E> Overrides: clear in class AbstractQueue<E>for...
LinkedBlockingQueue() 创建一个 LinkedBlockingQueue ,容量为 Integer.MAX_VALUE。 LinkedBlockingQueue(Collection<? extends E> c) 创建一个 LinkedBlockingQueue ,容量为 Integer.MAX_VALUE ,最初包含给定集合的元素,以集合的迭代器的遍历顺序添加。 LinkedBlockingQueue(int capacity) 创建一个具有给定(固定...
