多核处理器为并发编程打开了一扇扇新的大门,Java内置的多线程机制可以方便地实现多个并发程序的开发以及多任务同时执行,但是Java线程之间的通信对程序员完全透明,内存可见性问题很容易困扰Java开发人员,本文将简单分析基于内存模型的Java并发编程。-Multicore processors concurrent programming has opened a new door fan, built-in Java multithreading can easily achieve development and multi-task simultaneous execution of multiple concurrent programs, but the communication between the Java thread completely transparent to the programmer, memory problems are easily visible troubled Java developers, this article will analyze simple concurrent programming based on Java memory model.
