(1)ArrayBlockingQueue:是一个基于数组结构的有界阻塞队列,FIFO(先进先出)。 (2)LinkedBlockingQueue:一个基于链表结构的阻塞队列,此队列按FIFO (先进先出) 排序元素,吞吐量通常要高于ArrayBlockingQueue,静态工厂方法 Executors.newFixedThreadPool() 使用了这个队列。 (3)SynchronousQueue:一个不存储元素的阻塞队列。...

Producer-consumer before Java 5: using a List with wait/notifyPre Java 5, the common way to implement a producer-consumer pattern was to use a plain old LinkedList with explicit synchronization. When we add a "job" to the list, we call notify(); in another thread, the consumer is ...

本文主要讲解Java多线程:ThreadPoolExecutor+BlockingQueue线程池示例,我们来一起看下代码吧! 首先定义扩展线程池ExtThreadPoolExecutor ExtThreadPoolExecutor作用是对线程池的增强,如在初始化线程池时、在线程执行前、执行后等处可添加自定义逻辑。 public class ExtThreadPoolExecutor extends ThreadPoolExecutor{ ...
