在Java中,Executor Service是一个用于管理和调度线程执行的框架。它提供了一种简单而强大的方式来执行异步任务,并且可以管理线程池的大小、任务队列、线程的生命周期等。 在Executor Service中,依赖线程是指一个任务(也称为Callable或Runnable)依赖于其他任务的执行结果。当一个任务依赖于其他任务时,它必须等待其他任务完...

java并发 ExecutorCpmpletionService 实现ExecutorCompletionService的步骤 简介 在Java并发编程中,ExecutorCompletionService是一个方便的工具类,用于处理一批任务并获取它们的结果。它能够将多个任务提交给Executor执行,并将它们的结果按照完成的顺序返回给调用者。本文将详细介绍如何使用ExecutorCompletionService实现这个功能。

简介:java线程池ThreadPoolExecutor八种拒绝策略浅析 前言 谈到java的线程池最熟悉的莫过于ExecutorService接口了,jdk1.5新增的java.util.concurrent包下的这个api,大大的简化了多线程代码的开发。而不论你用FixedThreadPool还是CachedThreadPool其背后实现都是ThreadPoolExecutor。ThreadPoolExecutor是一个典型的缓存池化设计的...
参考之前ExecuteService中的介绍和实例,我们可以轻松理解这里代码的含义,首先判断任务是否为null,若是null,则抛出空指针,否则使用newTaskFor将任务(和返回值)封装成为FutureTask,再将其作为入参调用execute进行任务执行。最后将之前封装的FutureTask作为返回值返回。
