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。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。
代码语言：javascript复制public class Main {
public static void main(String[] args) {
Faculty fac = new Faculty("张三", 32, "33006", 2021, 9, 1, "讲师");
Student stu = new Student("李四", 19, "20201103", "202011");
Staff sta = new Staff("王五", 27, "32011", 2017, 7, 23, "教务员");
fac.show();
sta.show();
stu.show();
}
}
//基类 Role
class Role {
protected String name; //姓名
protected int age;
//构造方法
public Role() {
}
public Role(String name, int age) {
this.name = name;
this.age=age;
}
//Setter/Getter
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
//业务方法
public void show(){
System.out.print("我是" name "，年龄" age "岁。");
}
}
//派生类 Faculty 教员
class Faculty extends Role{
}
//派生类 Student 学生
class Student extends Role{
}
//派生类 Staff 职员
class Staff extends Role{
}输入样例:
代码语言：javascript复制输出样例:
代码语言：javascript复制我是张三，年龄32岁。工号是33006，2021年9月1日入职。是一名教师，讲师职称。
我是王五，年龄27岁。工号是32011，2017年7月23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。持续关注 有更多题目
