Java Review - 并发编程_DelayQueue原理&源码剖析

概述DelayQueue并发队列是一个无界阻塞延迟队列，队列中的每个元素都有个过期时间，当从队列获取元素时，只有过期元素才会出队列。队列头元素是最快要过期的元素。类图结构由该图可知DelayQueue内部使用PriorityQueue存放数据，使用ReentrantLock实现线程同步。另外，队列里...

Java Review - 并发编程_原子操作类原理剖析

概述JUC包提供了一系列的原子性操作类，这些类都是使用非阻塞算法CAS实现的，相比使用锁实现原子性操作这在性能上有很大提高。由于原子性操作类的原理都大致相同，我们以AtomicLong类的实现原理为例，并探讨JDK8新增的 LongAdder和LongAccumulator类的原理原子变量操作类JU...
