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. Eclip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
