java multithreading parallel-processing threadpoolexecutor 作为初学者,我了解了java中的threads和并发包,并阅读了有关ThreadPoolExecutor的文档,以了解getPoolSize()、getCorePoolSize()、getMaxPoolSize()之间的区别,并尝试在代码中实现相同的功能。 BIT OF BACKGROUND 据我所知,Executors.newFixedThreadPool(3)用...
在前面的一篇文章里我对java threadpool的几种基本应用方法做了个总结。Java的线程池针对不同应用的场景,主要有固定长度类型、可变长度类型以及定时执行等几种。针对这几种类型的创建,java中有一个专门的Executors类提供了一系列的方法封装了具体的实现。这些功能和用途不一样的线程池主要依赖于ThreadPoolExecutor,Schedu...
一段时间以来,我一直对 ThreadPoolExecutor 的默认行为感到沮丧,它支持我们很多人使用的 ExecutorService 线程池。引用 Javadocs:
