                              Java线程模型重点知识解析

                              时间:2015-08-29 17:53:19  来源:Java培训网  作者:IT培训网  已有:名学员访问该课程
                              你必须防止一个线程写入数据而另一个线程正在读取链表中的数据。为此目的,Java在进程间同步性的老模式基础上实行了另一种方法:管程(monitor)。管程是一种由C.A.R.Hoare首先定义的控制机制。

                              什么是Java线程模型,对于这个知识点我们又该如何学习,今天IT培训网就来给大家详细介绍下Java线程模型、优先级、同步性、消息传递等方面的知识点。
