package com.template;public class Shoes extends Shopping{@Overridepublic void buy() {// TODO Auto-generated method stubSystem.out.println("购买了一双鞋子");}@Overridepublic void pay() {System.out.println("支护宝付款");}}

package com.template;public abstract class Shopping {public void shopping() {userlogin();buy();pay();}//final方法不让子类继承public final void userlogin() {System.out.println("用户登录");}//抽象方法子类必须实现public abstract void  buy() ;//付款方式默认一种，子类可以重写public void pay() {System.out.println("使用银联支付");}}
