删除操作:从表头开始遍历,当找到该元素,储存该元素的前一个数prev, 它自己temp, 将prev.next的指针指向curr.next, 跳过当前元素。 #linked listclassNode:def__init__(self,data):self.data=data#节点的数据self.next=None#下一节点的指针def__repr__(self):returnstr(self.data)classLinkedList:def__init_...
Memory consistency effects: As with other concurrent collections, actions in a thread prior to placing an object into a ConcurrentLinkedQueue happen-before actions subsequent to the access or removal of that element from the ConcurrentLinkedQueue in another thread. 内部类Node实现了一些CAS方法, 用于节...
Queue常用的实现主要有ArrayBlockingQueue,LinkedBlockingQueue,Queue是一个保持先进先出的顺序队列,不允许随机访问队列中的元素。 ArrayList核心源码解读 ArrayList是一个底层用数组实现的集合,数组元素类型为Object类型,支持随机访问,元素有序且可以重复,它继承于AbstractList,实现了List, RandomAccess, Cloneable, java.io....
LinkedBlockingQueue的出队列方法,是先获取出队列的takeLock,然后再执行出队列方法。 take方法和poll方法前者在队列为空后,会阻塞出队列的线程,后者poll方法则不会在队列为空时阻塞出队列线程,会直接返回null。 无论是take方法还是poll方法都是调用的dequeue()方法执行的出队列,那么看一下dequeue()方法的实现吧。一直...

Singly linked list with links pointing front to back. How are you going to enqueue on the back pointer without mutating the current back link? That link is immutable. Doubly linked list -- same problem as #2; you have to mutate state. Linked lists make great mutable queues. The goal...
