JAVA第十一周作业


4、Cola公司的雇员分为以下若干类:(知识点:多态)


(1) ColaEmployee :这是所有员工总的父类,属性:员工的姓名,员工的生日月份。

方法:getSalary(int month) 根据参数月份来确定工资,如果该月员工过生日,则公司会额外奖励100 元。



package zuoye; public class ColaEmployee { String name;
int month; public ColaEmployee() { } public ColaEmployee(String name,int month){ this.name=name; this.month=month; } public double getSalary(int month) { return 0; } }

(2) SalariedEmployee :     ColaEmployee 的子类,拿固定工资的员工。

属性:月薪



package zuoye; public class SalariedEmployee extends ColaEmployee{
double monSalary; public SalariedEmployee(String name,int month,double monSalary) { super(name,month); this.monSalary=monSalary; } public double getSalary(int month) { if (super.month==month) { return monSalary +100; }else { return monSalary; } } }

(3) HourlyEmployee :ColaEmployee 的子类,按小时拿工资的员工,每月工作超出160 小时的部分按照1.5 倍工资发放。

属性:每小时的工资、每月工作的小时数



private double hours; private int mon; public HourlyEmployee(String name, int months, int birthday,double hours,int mon) { super(name, months, birthday); this.hours=hours; this.mon=mon; if(super.getBirthday()!=super.getMonths()&&super.getMonths()>=160) { System.out.println("员工"+name+months+"月的工资为"+(mon*160+(hours-160)*mon*1.5)); }else if(super.getBirthday()==super.getMonths()&&super.getMonths()>=160){ System.out.println("员工"+name+months+"月的工资为"+(mon*160+(hours-160)*mon*1.5+100)); }else if(super.getBirthday()==super.getMonths()&&super.getMonths()<160) { System.out.println("员工"+name+months+"月的工资为"+(mon*hours+100)); }else if(super.getBirthday()!=super.getMonths()&&super.getMonths()<160) { System.out.println("员工"+name+months+"月的工资为"+mon*hours); }

(4) SalesEmployee :ColaEmployee 的子类,销售人员,工资由月销售额和提成率决定。

属性:月销售额、提成率



package zuoye; public class SalesEmployee extends ColaEmployee { private
int monthSales; private double royaltyRate; public SalesEmployee(String name, int month, int monthSales, double royaltyRate) { super(name, month); this.monthSales = monthSales; this.royaltyRate = royaltyRate; } public double getSalary(int month) { if (super.month == month) { return monthSales * royaltyRate + 100; } else { return monthSales * royaltyRate; } } }
(5) 定义一个类Company,在该类中写一个方法,调用该方法可以打印出某月某个员工的工资数额,
写一个测试类TestCompany,在main方法,把若干各种类型的员工放在一个ColaEmployee 数组里,并单元出数组中每个员工当月的工资。


package zuoye; public class TestCompany { public static
void main(String[] args) { ColaEmployee[] all = { new SalariedEmployee("asd", 5, 30000), new HourlyEmployee("qwe", 4, 100, 300), new SalesEmployee("zxc", 3, 7000000, 0.3) }; for (int i = 0; i < all.length; i++) { new Company().getSalary(all[i],5); } } }
