PTA 校园角色类设计-2 JAVA

在校园角色类设计-1题的基础上，增加了部分要求，加粗部分为增加的内容： 学校需要构建综合系统，使用者包含多种角色。角色Role分两类：学生Student和雇员Employee；雇员又分为教员Faculty和职员Staff。 每个角色都有姓名、年龄、性别、电话号码。学生有学号、班级、班级职务（班长、副班长、学习委员等）。一个雇员有工号、入职日期、所在部门。教员有职称和专业。职员有职位称号。 请以如下Main类为基础，构建各个角色类，将代码补充完整。 public class Main { public static void main(String[] args) { // TODO Auto-generated method stub Faculty fac = new Faculty(“张三”,32,“33006”,“2019”,“10”,“25”,“讲师”); Student stu=new Student(“李四”,19,“20201103”,“202011”); Staff sta = new Staff(“王五”,27,“32011”,“2015”,“06”,“17”,“教务员”);
fac.setSex(‘男’); fac.setTel(“13600770077”); fac.setDepartment(“数信学院”); fac.setMajor(“数学”); stu.setSex(‘女’); stu.setTel(“18000009999”); stu.setPosition(“班长”); sta.setSex(‘男’); sta.setTel(“18966666666”); sta.setDepartment(“航制学院”); Scanner input = new Scanner(System.in); int i = input.nextInt(); /* 使用多态根据用户的输入，输出不同的角色人物的信息， 输入1：教员 输入2：学生 输入3：职员 其他输入：输出"Wrong Format" */ } }
