Java经理与员工的差异实现方法

import java.util.Date;     

public class Employee {

    private String name;        //员工的姓名
    private double salary;      //员工的工资
    private Date birthday;      //员工的生日

    public String getName() {       //获取员工的姓名
        return name;
    }

    public void setName(String name) {  //设置员工的姓名
        this.name = name;
    }

    public double getSalary() {     //获取员工的工资
        return salary;
    }

    public void setSalary(double salary) {  //设置员工的工资
        this.salary = salary;
    }

    public Date getBirthday() {     //获取员工的生日
        return birthday;
    }

    public void setBirthday(Date birthday) {        //设置员工的生日
        this.birthday = birthday;
    }

}
public class Manager extends Employee {
    private double bonus;// 经理的奖金

    public double getBonus() {// 获得经理的奖金
        return bonus;
    }

    public void setBonus(double bonus) {// 设置经理的奖金
        this.bonus = bonus;
    }
}
import java.util.Date;

public class Test {
    public static void main(String[] args) {
        Employee employee = new Employee();//创建Employee对象并为其赋值
        employee.setName("Java");
        employee.setSalary(100);
        employee.setBirthday(new Date());
        Manager manager = new Manager();//创建Manager对象并为其赋值
        manager.setName("明日科技");
        manager.setSalary(3000);
        manager.setBirthday(new Date());
        manager.setBonus(2000);
        //输出经理和员工的属性值
        System.out.println("员工的姓名：" + employee.getName());
        System.out.println("员工的工资：" + employee.getSalary());
        System.out.println("员工的生日：" + employee.getBirthday());
        System.out.println("经理的姓名：" + manager.getName());
        System.out.println("经理的工资：" + manager.getSalary());
        System.out.println("经理的生日：" + manager.getBirthday());
