- 编程题：公安人员的管理系统
1） 学生类：
a) 属性：
i. 身份号—默认没有，需要手动进行输入
ii. 姓名
iii. 性别
iv. 年龄
v. 密码
vi. 居住地址
vii. 注册日期
viii. 人员的信誉程度（
- 0：无犯罪历史，
- 1：有过轻度犯罪历史
- 2：严重犯罪历史
- 3：杀人罪但是有期徒刑
- 4：杀人罪并执行死刑
- 5：个人荣誉小贴士
- 6：国家级别荣誉奖章）
ix. 文化程度（
- 0：没有教育历史（包括幼儿园）
- 1：小学文化
- 2：初中文化
- 3：高中文化
- 4：大学文化（硕士生）
- 5：研究生
- 6：博士生
- 7：教授）
--默认是没有教育历史
x. 学习次数
b) 行为：
i. 学习：
- 传入的内容是从学习类列表中随机抽取，也可以自己输入学习编号
- 逻辑：先判断学习的上一级内容是否已经达到，如果达到则学习，并将本对象的文化程度修改为相对应的级别，如果没达到，则抛出学历级别未达到异常。学习完后则学习次数可以加1
2） 学习类列表：
a) 可学习的内容如下
i. 小学课本
ii. 高中课本
iii. 大学课本
iv. 研究生课本
v. 博士生课本
vi. 教授课本
vii. 厨师技能
viii. 修汽车技能
3） 本地公安局类：
a) 属性：公安局人员备案库（最大存储200个）
b) 移民：（传入当前用户的对象）
-
先判断当前公安局人员备案库里是否存在当前用户
a) 没有的话则打印您是未成年人还不能移民，
b) 若有则判断当前的人员的信誉程序是否有无犯罪历史
i. 有的话则不能移民，
ii. 若没有犯罪历史，
-
再判断文化程度是否达到大学文化
a) 没有则需要再等待1年审核时间
b) 若达到大学文化，则可以移民，并将本地公安局和国家人员管理库的当前人员永久删除。
4） 国家人员管理库：
a) 属性：全国国家安全总局人员备案库（最大存储3000000）
b) 行为：
i. 查询人员：
- 逻辑：传入人员的对象，并判断当前是否存在，不存在返回false，存在返回true;
ii. 人员的入库：
- 逻辑：传入人员对象
a) 先看当前库是否存在，若存在则打印已存在，否则注册
iii. 人员的删除
-
逻辑：传入人员对象
a) 则先看是否存在，若存在则删除，不存在则打印：人员身份未备案
