编写工资系统实现不同类型员工(多态)的按月发放工资。如果当月出现某个Employee对象的生日则将该雇员的工资增加100元。实验说明1定义一个Employee类该类包含private成员变量name,number,birthday其中birthday 为MyDate类的对象
提供必要的构造器
abstract方法earnings(),返回工资数额
toString()方法输出对象的name,number和birthday。2MyDate类包含:
private成员变量year,month,day
提供必要的构造器
toDateString()方法返回日期对应的字符串xxxx年xx月xx日3定义SalariedEmployee类继承Employee类实现按月计算工资的员工处理。
该类包括private成员变量monthlySalary
提供必要的构造器
实现父类的抽象方法earnings(),该方法返回monthlySalary值
toString()方法输出员工类型信息及员工的namenumber,birthday。比如SalariedEmployee[name ,number ,birthdayxxxx年xx月xx日]4参照SalariedEmployee类定义HourlyEmployee类实现按小时计算工资的员工处理。该类包括
private成员变量wage和hour
提供必要的构造器
实现父类的抽象方法earnings(),该方法返回wage*hour值
toString()方法输出员工类型信息及员工的namenumber,birthday。5定义PayrollSystem类创建Employee变量数组并初始化该数组存放各类雇员对象的引用。
利用循环结构遍历数组元素输出各个对象的类型,name,number,birthday,以及该对象生日。
当键盘输入本月月份值时如果本月是某个Employee对象的生日还要输出增加工资信息。//提示
//定义People类型的数组People c1[]new People[10];
//数组元素赋值
c1[0]new People(John,0001,20);
c1[1]new People(Bob,0002,19);
//若People有两个子类Student和Officer则数组元素赋值时可以使父类类型的数组元素指向子类。
c1[0]new Student(John,0001,20,85.0);
c1[1]new Officer(Bob,0002,19,90.5); package chapter08_oop3.src.com.atguigu07._abstract.exer2;/*** ClassName: Employee* Package: chapter08_oop3.src.com.atguigu07._abstract.exer2* Description:** 1定义一个Employee类该类包含** private成员变量name,number,birthday其中birthday 为MyDate类的对象* 提供必要的构造器* abstract方法earnings(),返回工资数额* toString()方法输出对象的name,number和birthday。** Author 小白* Create 2024/4/4 12:48* Version 1.0*/
