办公信息化管理系统案例

任务描述

一、语言和环境

• 实现语言
  Java语言
• 环境要求及开发工具
  JDK、Eclipse

二、程序整体要求

1. 划分功能模块，根据题目要求设置不同的类，在类中实现相应功能的管理。
2. 类的标识要清楚易懂，代码结构要层次分明，代码编辑思路要清晰、整洁。
3. 要求Java代码书写、命名符合规范，属性所属数据类型要准确合理，在代码中添加必要的注释
4. 程序运行效果与提供的页面效果图、结构保持一致，信息间分隔符“=”号数量不做统一要求，文字大小、颜色也不做统一要求
5. 作业完成后发表在自己的博客上

三、思路分析：

由场景和运行效果，可以分析出项目中可以抽取如下类（要求编码时注意面向对象思想及封装特性的应用）：

• 部门类：
  类型描述：能够描述部门编号、部门名称、员工数组、统计部门中的员工个数
  要求：设定方法统计该部门员工个数
  提示：部门类的属性有四个，分别是部门编号，部门名称，员工数组 和 统计变量 ，具体是市场部还是人事部，是通过部门类的对象来表示的，如果是市场部的对象，那么添加并统计的就是市场部的人数，同样如果是人事部的对象，添加并统计的就是人事部的人数
• 职务类：
  类型描述：能够描述职务编号、职务名称
• 员工类：类型描述：能够描述员工姓名、工号、年龄、性别、所属部门、职务信息要求:

• • 设定方法限定年龄只能是18--65之间,反之则设置默认为18岁
  • 设定方法限定性别只能是“男”或者“女”,反之则设置默认为"男"
  • 设定方法，实现员工自我介绍信息，将员工信息作为字符串返回

• 测试类：
  类型描述：测试程序，并参照效果图输出结果
