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。
(2) SalariedEmployee : ColaEmployee 的子类,拿固定工资的员工。
- 属性:月薪
(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
(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
(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 qc; public class ColaEmployee { String name; int month; public ColaEmployee() { super(); } public ColaEmployee(String name, int month) { super(); this.name = name; this.month = month; } public double getSalary(int month){ return 0; } }
package qc; public class SalariedEmployee extends ColaEmployee { double salary; public SalariedEmployee() { super(); } public SalariedEmployee(String name,double salary,int month) { super(name,month); this.salary = salary; } public double getSalary(int month){ if(super.month==month){ return salary+100; } else{ return salary; } } }
package qc; public class HourlyEmployee extends ColaEmployee{ double hoursalary; double hour; public HourlyEmployee() { super(); } public HourlyEmployee(String name,double hoursalary, double hour,int month) { super(); this.hoursalary = hoursalary; this.hour = hour; } public double getSalary(int month){ if(super.month==month){ if(hour>160){ return hoursalary*160+(hour-160)*1.5*hoursalary+100; }else{ return hoursalary*160+100; } }else{ if(hour>160){ return hoursalary*160+(hour-160)*1.5*hoursalary; }else{ return hoursalary*160; } } } }
package qc; public class Sales extends ColaEmployee{ double monthsalary; double reward; public Sales() { super(); } public Sales(String name,double monthsalary, double reward,int month) { super(); this.monthsalary = monthsalary; this.reward = reward; } public double getSalary(int month){ if(super.month==month){ return monthsalary*reward+100; }else{ return monthsalary*reward; } } }
package qc; public class Company { public void getSalary(ColaEmployee c, int month){ System.out.println(c.name + "在" + month + "月月薪为" + c.getSalary(month) + "元"); } }
package qc; public class TestCompany { public static void main(String[] args) { // TODO Auto-generated method stub ColaEmployee[] all = { new SalariedEmployee("张三", 8000, 9), new HourlyEmployee("李四", 5, 10, 3), new Sales("王二", 50000,0.5, 3) }; for (int i = 0; i < all.length; i++) { new Company().getSalary(all[i],5); } } }
