J.U.C 为常用的集合提供了并发安全的版本,前面讲解了 map 的并发安全集合 ConcurrentHashMap,List 并发安全集合 CopyOnWriteArrayList,Set 并发安全集合 CopyOnWriteArraySet,本篇文章就来介绍并发安全的队列 ConcurrentLinkedQueue。 ConcurrentLinkedQueue 是一个基于链接节点的无边界的线程安全队列,采用非阻塞算法实现线程...
you need to sum up all the samples to produce a single cumulative sample which is the sound value you write to theoutput file for that time step. When the time for the next note has been reached, you pluck the specified string (unless youreach the end song value in which case you ...

We simply check for the rear pointer to reach at MAXSIZE to check that the queue is full because we are utilizing a single dimension array to create the queue. The algorithm will be different if we retain the queue as a circular linked list. The isfull() function’s algorithm − ...

A session is a single-threaded context for producing and consuming messages. You can create multiple producers and consumers for a session, but you are restricted to using them serially. In effect, only a single logical thread of control can use them. A session supports reliable delivery through...
