JMM怎么记

Based on the deficiency, this paper analyses Java Memory Model ( JMM), the reason for DCL invalidation and the interior mechanism of "ThreadLocal". The strategy to design the object of class by singleton model is proposed.

针对这些不足，本文结合实例分析了Java内存模型（JMM）、DCL失效原因以及ThreadLocal的内部运行机制，给出了将类的对象设计成Singleton模式的策略。

In the same time, Java Memory Model ( JMM) allows compilers to change the executing order of programs in the optimization progress. This will lead to lots of unexpected errors in multithreaded Java programs.

同时，Java内存模型JMM（Java Memory Model）允许编译器在优化过程中改变程序的执行顺序，这会让多线程Java程序产生许多意想不到的错误。

We can extend the lock granularity technique to handle this situation, although we must be careful as there are some potential Java Memory Model ( JMM) hazards associated with this approach.

我们可以扩展锁粒度技术以应付这种情形，尽管我们必须很小心，因为有与这种方法有关的一些Java内存模型（Java Memory Model，JMM）危害。
