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、性别。学生有学号、班级。一个雇员有工号、入职日期。教员有职称。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) { 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.show(); sta.show(); stu.show(); } } 输入格式: 无 输出格式: 我是张三,年龄32岁。工号是33006,2019年10月25日入职。是一名教师,讲师职称。 我是王五,年龄27岁。工号是32011,2015年6月17日入职。是一名教务员。 我是李四,年龄19岁。学号是20201103,来自202011班。 输入样例: 在这里给出一组输入。例如: 输出样例: 在这里给出相应的输出。例如: 我是张三,年龄32岁。工号是33006,2019年10月25日入职。是一名教师,讲师职称。 我是王五,年龄27岁。工号是32011,2015年6月17日入职。是一名教务员。 我是李四,年龄19岁。学号是20201103,来自202011班。
