“人才管理系统”
类描述：
人才信息，属性：姓名，性别，年龄，专业，毕业学校，掌握技能（list集合）
个人简历，继承人才信息，属性：个人简介
猎头公司，属性：公司名称，地址
接口描述：
1、增加人才信息
2、查询人才信息
3、根据年龄向控制台查询人才信息
4、根据专业向控制台查询人才信息
5、查询出技能中掌握java的人才信息
6、猎头公司可以查看人才系统所有人才
7、猎头公司根据选择的人才查看个人的简介
要求：
1、创建三个包，一个包为entity，存放类；一个包为service，存放所有属性接口；一个包为controller，存放测试类
2、增加人才信息时，每个人才信息创建一个文件夹单独存放，文件夹名称为姓名，文件夹内容为个人信息txt和个人介绍txt
3、循环展示人才管理系统的文件夹，通过判断控制台输入内容，查询到相应的人才文件夹，读取文件夹中txt内容，在控制台展示
4、所有输出语句均写在测试类中，方法🈯只做业务操作
5、类名要求按照帕斯卡命名法，首字母大写，其余单词字母均大写，例如：Student（学生类）；属性要求按照匈牙利命名法命名，属性名=数据类型+描述，例如strName（姓名），intAge（年龄）；方法名要求按照驼峰命名法命名，首字母小写，其余单词首字母大写，例如addStudent（新增学生）
第一次提交
总结：
-
在这里不知道怎么通过文件添加对象里面的list集合这个元素，所以浪费了许多时间，我这次的解决方法是重写toString方法，如何将每一个属性使用","分隔，然后依次为对象赋值 -
第二个问题就是，流的使用还不是非常熟练，尤其是缓冲流的使用，有一点模糊，但是现在清楚了：字节流的缓冲流，不行首先定义字节流，然后通过这个定义的内容传入缓冲流的括号里面；字符流的缓冲流定义也是通过首先定义的字符流，但是这个多了两种方法，那就是FileReader和FileWriter，不过这个和定义字符流的标准方法差不多并且用法大致相同，应该就是为了方便，所以才出现了这两个方法 -
