Class.getDeclaredClasses介绍

[英]Returns an array containing Class objects for all classes and interfaces that are declared as members of the class which this Class represents. If there are no classes or interfaces declared or if this class represents an array class, a primitive type or void, then an empty array is returned.
[中]返回一个数组，该数组包含声明为该类所表示的类的成员的所有类和接口的类对象。如果没有声明类或接口，或者该类表示数组类、基元类型或void，则返回空数组。
