Answer 1

给个例子做参考，文件要保存为MyTest.java，或者修改代码里的MyTest为你的文件名：

class Staff{
    String name;
    int age;
    String sex;
    public Staff(String name, int age, String sex){
        this.name =name;
        this.age = age;
        this.sex = sex;
    }
    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;
    }
    public String getSex() {
        return sex;
    }
    public void setSex(String sex) {
        this.sex = sex;
    }
    public void showInfo(){
        System.out.println("姓名："+this.name+" 年龄："+this.age+" 性别："+this.sex);
    }
} 

class Manager extends Staff {
    String post;
    int salary;

    public Manager(String name, int age, String sex, String post, int salary) {
        super(name, age, sex);
        this.post = post;
        this.salary = salary;
    }

    public String getPost() {
        return post;
    }

    public void setPost(String post) {
        this.post = post;
    }

    public int getSalary() {
        return salary;
    }

    public void setSalary(int salary) {
        this.salary = salary;
    }
    public void showInfo(){
        System.out.println("姓名："+this.name+" 年龄："+this.age+" 性别："+this.sex+" 职务："+this.post+" 年薪："+this.salary);
    }

}

class Employee extends Staff {
    String department;
    int monthly;
    public Employee(String name, int age, String sex, String department, int monthly) {
        super(name, age, sex);
        this.department = department;
        this.monthly = monthly;
    }
    public String getDepartment() {
        return department;
    }
    public void setDepartment(String department) {
        this.department = department;
    }
    public int getMonthly() {
        return monthly;
    }
    public void setMonthly(int monthly) {
        this.monthly = monthly;
    }
    public void showInfo(){
        System.out.println("姓名："+this.name+" 年龄："+this.age+" 性别："+this.sex+" 部门："+this.department+" 月薪："+this.monthly);
    }
}

public class MyTest{
    public static void main(String[] args) {
        Manager manager = new Manager("张三", 38, "男", "总经理", 3000000);
        Employee employee = new Employee("李四", 28, "女", "研发部", 5300);
        manager.showInfo();
        employee.showInfo();
    }
}
