一.说明

1.Class<? super T> getSuperclass():返回本类的父类

2.Type getGenericSuperclass():返回本类的父类,包含泛型参数信息

二.例子

1.ClassA.java

public class ClassA <T>{ private T obj; public void setObject(T obj) { this.obj = obj; } public T getObject() { return obj; } }

2.Test.java

import java.lang.reflect.Type; import java.lang.reflect.ParameterizedType; public class Test<T> extends ClassA<T>{ public static void main(String args[]) throws Exception{ System.out.println("======getSuperclass======:"); System.out.println(Test.class.getSuperclass().getName()); System.out.println("======getGenericSuperclass======:"); Type t = Test.class.getGenericSuperclass(); System.out.println(t); if (ParameterizedType.class.isAssignableFrom(t.getClass())) { System.out.print("----------->getActualTypeArguments:"); for (Type t1:((ParameterizedType)t).getActualTypeArguments()) { System.out.print(t1 + ","); } System.out.println(); } } }

输出结果:

======getSuperclass======:

ClassA

======getGenericSuperclass======:

ClassA<T>

----------->getActualTypeArguments:T,
