先写一个父类

public class Staff {
    
     //创建员工类
    private String name; //创建名字，年龄，性别
    private int age;
    private char sex;

    public Staff(String name, char sex, int age) {
    
     //员工类的构造方法
        this.name = name;
        this.age = age;
        this.sex = sex;
    }
    public String print() {
    
     //显示数据的方法
        return "姓名" + this.getName() + " " + "年龄" + this.getAge() + " " + "性别" + this.getSex() + " ";
    }
    public String getName() {
    
    
        return name;
    }
    public void setName(String name) {
    
    
        this.name = name;
    }
    public char getSex() {
    
    
        return sex;
    }
    public void setSex(char sex) {
    
    
        this.sex = sex;
    }
    public int getAge() {
    
    
        return age;
    }
    public void setAge(int age) {
    
    
        this.age = age;
    }
}

写两个子类继承父类

class Management extends Staff {
    
     //创建管理层类并继承员工类
    private String post; //管理层类自己的属性，职务和年薪
    private int annualSalary;

    public Management(String name, char sex, int age, String post, int annualSalary) {
    
    
        super(name, sex, age);
        this.annualSalary = annualSalary;
        this.post = post;
    }
    public String print() {
    
     //输出员工类有的属性和管理层类特有的属性
        return super.print() + "职务" + this.getPost() + " " + "年薪" + this.getAnnualSalary() + " ";
    }
    public String getPost() {
    
    
        return post;
    }
    public void setPost(String post) {
    
    
        this.post = post;
    }
    public int getAnnualSalary() {
    
    
        return annualSalary;
    }
    public void setAnnualSalary(int annualSalary) {
    
    
        this.annualSalary = annualSalary;
    }
}
class Worker extends Staff {
    
     //创建职员类并继承员工类
    private String department; //职员类自己的属性，部门和月薪
    private int monthSalary;

    public Worker(String name, char sex, int age, String department, int monthSalary) {
    
    
        super(name, sex, age);
        this.department = department;
        this.monthSalary = monthSalary;
    }
    public String print() {
    
    
        return super.print() + "姓名" + this.getDepartment() + " " + "年龄" + this.getMonthSalary();
    }
    public String getDepartment() {
    
    
        return department;
    }
    public void setDepartment(String department) {
    
    
        this.department = department;
    }
    public int getMonthSalary() {
    
    
        return monthSalary;
    }
    public void setMonthSalary(int monthSalary) {
    
    
        this.monthSalary = monthSalary;
    }
}

写一个测试类

public class StaffTest {
    
    
    public static void main(String[] args) {
    
    
        Worker a = new Worker("ZhangSan",'男',34,"监管",6000);
        a.print();
        Management b = new Management("李四",'男',45,"总监",14000);
        b.print();
    }
}
