If one evaluation modifies a memory location, and the other reads or modifies the same memory location, and if at least one of the evaluations is not an atomic operation, the behavior of the program is undefined (the program has a data race) unless there exists a happens-before relationship...
1. Queue Array Basic OperationsWrite a C program to implement a queue using an array. Programs should contain functions for inserting elements into the queue, displaying queue elements, and checking whether the queue is empty or not. Sample Solution:...

1. 共享内存 share memory (Value、Array) (默认上锁)基本特点:(1)共享内存是一种最为高效的进程间通信方式,进程可以直接读写内存,而不需要任何数据的拷贝。(2)为了在多个进程间交换信息,内核专门留出了一块内存区,可以由需要访问的进程将其映射到自己的私有地址空间。进程就可以直接读写这一块内存而不需要进行...
lock,锁,ArrayBlockingQueue出列入列都必须获取该锁,两个步骤公用一个锁 notEmpty,出列条件 notFull,入列条件 入对 ArrayBlockingQueue提供了诸多方法,可以将元素加入队列尾部。 add(E e) :将指定的元素插入到此队列的尾部(如果立即可行且不会超过该队列的容量),在成功时返回 true,如果此队列已满,则抛出 Illegal...

java.util.concurrent.ArrayBlockingQueue 代码如下 View Code 0. ArrayBlockingQueue简介 用循环数组实现的有界阻塞队列,线程安全。初始化时要求设定容量,在队列满时继续put元素会被阻塞,在队列为空时继续poll元素也会被阻塞。 ArrayBlockingQueue也提供了非阻塞以及可中断的插入/提取元素的方法。
