Java 并发基础

Java 并发基础标签： Java基础线程简述线程是进程的执行部分,用来完成一定的任务; 线程拥有自己的堆栈,程序计数器和自己的局部变量,但不拥有系统资源, 他与其他线程共享父进程的共享资源及部分运行时环境,因此编程时需要小心,确保线程不会妨碍同一进程中的其他线程; 多线程优势进程之间不能...

Java并发编程系列之一：并发机制的底层原理

前言并发编程的目的是让程序运行更快，但是使用并发并不定会使得程序运行更快，只有当程序的并发数量达到一定的量级的时候才能体现并发编程的优势。所以谈并发编程在高并发量的时候才有意义。虽然目前还没有开发过高并发量的程序，但是学习并发是为了更好理解一些分布式架构。那么当程序的并发量不高，比如是单线程的程序...

【Java并发之】BlockingQueue

本文主要讲的是并发包中涉及到的集合，关于普通集合，请参考【java 集合概览】一、什么是BlockingQueue BlockingQueue即阻塞队列，从阻塞这个词可以看出，在某些情况下对阻塞队列的访问可能会造成阻塞。被阻塞的情况主要有如下两种： 1. 当队列满了的时候进行入队列操作 2. 当队...

java并发编程学习：用 Semaphore （信号量）控制并发资源

并发编程这方面以前关注得比较少，恶补一下，推荐一个好的网站：并发编程网 - ifeve.com，上面全是各种大牛原创或编译的并发编程文章。今天先来学习Semaphore（信号量），字面上看，根本不知道这东西是干啥的，借用并发工具类（三）控制并发线程数的Semaphore一文中的交通红绿信号灯的例...
