自己学习编写的程序,有很多不足之处请各位多多指正,谢谢大家!
系统需求:
1. 项目1中的功能。
2. 新增“会员等级管理”:
等级体系定义:初级、中级、高级。不同的等级享受不同的折扣额度: 不打折、9折、8折。
3. 新增“高级会员生日祝福功能”:
根据高级会员的生日,系统在当日的早上8:00,自动发送文字类型的生日祝福。
4. 系统可以根据“姓名”查询并输出他的等级。
5. 系统可以根据“会员编号”计算并输出经过打折以后实际应付的金额。
程序入口:
public class Run { public static void main(String[] args) { new SendBlessing(); new Login(); new MemberSystem(); } }
生日祝福:

登录程序:
