需求

编写一个Employee类，声明方法为抽象类，包含：name、id、salary三个属性。提供必要的构造器和抽象方法：work（）。对于Manager类来说，他既是员工，还具有奖金（bonnus）的属性。请使用继承的思想，设计CommonEmployee类和Manager类，要求类中提供必要的方法进行属性访问，实现work（）。【继承+抽象】

实现

Employee

package test;
abstract public class Employee {
    private String name;
    private int id;
    private double salary;
    public Employee(String name, int id, double salary) {
        this.name = name;
        this.id = id;
        this.salary = salary;
    }
    //将work做成一个抽象方法
    public abstract void work();
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public double getSalary() {
        return salary;
    }
    public void setSalary(double salary) {
        this.salary = salary;
    }
}

Manager

package test;
public class Manager extends Employee {
    private double bonus;
    public Manager(String name, int id, double salary) {
        super(name, id, salary);
    }
    public double getBonus() {
        return bonus;
    }
    public void setBonus(double bonus) {
        this.bonus = bonus;
    }
    @Override
    public void work() {
        System.out.println("经理 " + getName() + " 工作中...");
    }
}

CommonEmployee

package test;
public class CommonEmployee extends Employee{
    public CommonEmployee(String name, int id, double salary) {
        super(name, id, salary);
    }
    @Override
    public void work() {
        System.out.println("普通员工 " + getName() + " 工作中...");
    }
}

Main

package test;
public class Main {
    public static void main(String[] args) {
        Manager wty2002 = new Manager("WTY2002", 1, 500000);
        wty2002.setBonus(1000);
        wty2002.work();
        CommonEmployee tom = new CommonEmployee("Tom", 2, 2000);
        tom.work();
    }
}
