类名称：Class
方法名：getSuperclass

Class.getSuperclass介绍

[英]Returns the Class object which represents the superclass of the class represented by this Class. If this Class represents the Object class, a primitive type, an interface or void then the method returns null. If this Class represents an array class then the Object class is returned.
[中]返回表示该类所表示的类的超类的Class对象。如果该类表示对象类、基元类型、接口或void，则该方法返回null。如果该类表示数组类，则返回对象类。
