Java实现宠物商店管理系统

本文实例为大家分享了Java实现宠物商店管理系统的具体代码,供大家参考,具体内容如下

一、实验目的

1.掌握java类的继承、多态等的基本概念;

2.掌握简单的信息管理系统的设计与实现。

二、实验环境

实验建议在安装了以下软件的计算机上完成:

1. Windows xp/win7/win8/win10操作系统
2. JDK 1.6以上版本
3. Eclipse或NetBeans IDE或EditPlus或其它开发工具

三、实验内容与要求

(一) 问题描述

要求采用java面向对象的基本知识,实现宠物商店管理系统。

(二) 实验要求

1、宠物商店有狗和猫两种动物,请为这两种动物创建各自的类,而且它们都继承宠物类,为这些类定义基本的属性和方法;

2、为宠物商店也创建一个类,该类有基本属性,比如商店名称等,还有宠物笼子的属性,此外,还具备一些方法,比如:买进宠物、销售宠物、清点宠物库存、销售统计和盈利情况等;

3、实现买进宠物的方法,输入狗或猫的基本属性和进货价格,并把该买进的宠物放进宠物笼子;

4、实现销售宠物的方法,输入狗或猫的基本属性和销售价格,并把宠物从宠物笼子取出;

5、实现清点宠物库存方法,列出所有库存的宠物清单;

6、实现销售和盈利统计,查询所有已销售的宠物清单,包括进货价格和销售价格,还有总利润;

四、实现提示

1. 宠物笼子采用数组实现,数组的数据类型为宠物类;

 2. 销售清单也采用数组实现。

五、代码
