Chapter 7. Packages
The hierarchical naming structure for packages is intended to be convenient for organizing related packages in a conventional manner, but has no significance in itself other than the prohibition against a package having a subpackage with the same simple name as a top level type (§7.6) declared in that package.
包的分级命名结构旨在以一种传统的方式组织相关的包，但是除了禁止对包中具有与该包中声明的顶级类型（7.6）相同的子包的包的禁止外，它本身没有什么意义。
