类名称：Reflection
方法名：getPackageName

Reflection.getPackageName介绍

[英]Returns the package name of clazz according to the Java Language Specification (section 6.7). Unlike Class#getPackage, this method only parses the class name, without attempting to define the Package and hence load files.
[中]根据Java语言规范（第6.7节）返回clazz的包名。与类#getPackage不同，该方法只解析类名，而不尝试定义包，从而加载文件。
