juc's Introduction

juc项目简单说明

  • 这是java.util.concurrent并发包中的学习小项目，对一些并发包下的常用类的测试和demo。

目前接入的知识（持续更新中）

atomic package：

  1. 简单实现CAS**的DEMO
  2. Automic包中的原子类去实现线程安全的 i++ 操作

collection package:

  1. 应用"写入时复制"的copyOnWriteArrayList的Demo
  2. 实现一个简单的cow的Map容器。

communication package:

  1. 循环打印ABC这道题的应用Condition实现的Demo

countdownLatch package:

  1. 使用闭锁countDownLatch实现统计多个线程计算的时间消耗

lock package:

  1. 使用lock去解决线程安全问题
  2. 经典的消费者生产者问题，应用三种方式。（wait/notify、await/signal、阻塞队列）
  3. 线程八锁问题

newthread package:

  1. 创建线程的几种方式 主流的线程池、继承Thread、实现Runnable接口、实现Callable接口等

volatiletest package:

  1. 对volatile保证内存可见性做了Demo。

readWriteLock package:

  1. 读写锁 注意读/锁线程，锁/锁线程应该互斥。而读/读线程可以共享

threadPool package:

  1. 线程池简单应用
  2. 线程调度（应用 scheduledThreedPool）
  3. ThreadPoolExecutor源码分析系列： （1）ctl变量

threadLocal package:

  1. ThreadLocal的一个工具类
  2. 个人总结的ThreadLocal

semaphore package:

  1. 利用Semaphore实现的一个有边界的容器。这里是利用了其中的许可来实现最大的边界，来源于《java并发编程实战》。

lesson.wwj.juc.* package

  1. 这个是学习一个并发的课程，主要是用来查漏补缺

写的不好的地方希望指正
