代码如下:
1 package com.sina.demo; 2 interface IMessageService{ 3 public void send(); 4 } 5 interface IChannel{ 6 public boolean connect(); 7 } 8 abstract class AbstractBase{} 9 class Mail extends AbstractBase implements IMessageService,IChannel{ 10 @Override 11 public boolean connect() { 12 return true; 13 } 14 @Override 15 public void send() { 16 if(this.connect()) { 17 System.out.println("【信息发送】www.sina.com.cn"); 18 } 19 } 20 } 21 public class JavaReflectDemo { 22 public static void main(String[] args) { 23 Class<?> cls = Mail.class; 24 Package pkg = cls.getPackage(); 25 System.out.println("包名称:"+pkg.getName()); 26 Class<?> parent = cls.getSuperclass(); 27 System.out.println("父类名称:"+parent.getName()); 28 Class<?> clazz[] = cls.getInterfaces(); 29 for(Class<?> temp:clazz) { 30 System.out.println("父接口名称:"+temp); 31 } 32 } 33 }
运行结果:
包名称:com.sina.demo 父类名称:com.sina.demo.AbstractBase 父接口名称:interface com.sina.demo.IMessageService 父接口名称:interface com.sina.demo.IChannel
