1、要求利用面向对象的方法以及Java的编程思想来完成系统的设计；

2、要求在设计的过程中，建立清晰的类层次；

3、在系统设计中要分析和定义各个类，每个类中要有各自的属性和方法；

4、在系统的设计中，要求运用面向对象的机制（继承、派生及多态性）来实现系统功能。

5、在基本要求达到后，可进行创新设计，如根据查找结果进行修改的功能及设计出比较友好的界面等。

6、职工信息包括职工号、姓名、性别、年龄、学历、工资、住址、电话等（职工号不重复）。设计“职工信息管理系统”，使之能提供以下功能：

-1, requires the use of object-oriented Java programming methods and ideas to complete the design of the system　2, requiring the design process, establish a clear hierarchy of classes　3, in the system design to analyze and define the various classes, each class the properties and methods have their own　4, in the design of the system, requiring the use of object-oriented mechanism (inheritance, and polymorphism derived) to implement the system function. 5, after the basic requirements to achieve, can be innovative designs, such as the modification of the search results based on function and design a more friendly interface. 6, staff workers, including information number, name, sex, age, education, salary, address, phone, etc. (Staff numbers are not repeated). Design " Employee Information Management System" , so that it can provide the following features: 1) the menu system to work the way　2) Employee information input function (Employee information stored with the file)　3)
