使用DAO模式开发宠物管理系统---hellokitty
宠物有狗和企鹅。
狗的属性有：编号、名称、亲密值、健康值、品种、所属主人编号。
企鹅的属性有：编号、名称、亲密值、健康值、性别、所属主人编号。
该系统中主人可以领养宠物，主人的属性有：编号、用户名、密码、姓名、地址、电话。
要求将狗和企鹅的数据保存到同一张表中除所属主人编号、品种、性别外，其余列均不允许为空。主人编号为空表示该宠物未被人领养。
创建宠物表与主人表，狗和企鹅、主人各初始化5条以上的记录用于测试。
编写程序实现以下功能：
1. 主人可以登录到系统中完成下列操作：
2. 主人可以查看当前系统中未被领养的宠物
3. 主人可以领养宠物
4. 主人可以查看自己已领养的所有宠物的信息
5. 主人可以根据编号查询宠物信息
6. 主人可以弃养自己已领养的宠物
7. 退出系统
我是java的初学者，中间代码也有可能有错误的，或是不够简洁的。。。
