熟悉ubuntu的朋友不用看了,这篇文章是给刚刚接触ubuntu的朋友查看的。我们知道在ubuntu下安装软件可能很多都是用apt-get命令,就像在红帽系列的linux系统中是用rpm一样,在红帽系统中,我们要查看一个已安装的软件都在我们系统中安装了什么,可以使用命令rpm -ql softwarename,那么在ubuntu下怎么查看呢?使用命令apt-file list softwarena

实现原理锁分离 (Lock Stripping)ConcurrentHashMap允许多个修改操作并发进行,其关键在于使用了锁分离技术。它使用了多个锁来控制对hash表的不同部分进行的修改。ConcurrentHashMap内部使用段(Segment)来表示这些不同的部分,每个段其实就是一个小的hash table,它们有自己的锁。只要多个修改操作发生在不同的段上,它们就可以并发进行。有些方法需要
