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 huada; 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 huada; 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("名字"+name+months+"工资为"+(mon*160+(hours-160)*mon*1.5)); }else if(super.getBirthday()==super.getMonths()&&super.getMonths()>=160){ System.out.println("名字"+name+months+"工资为"+(mon*160+(hours-160)*mon*1.5+100)); }else if(super.getBirthday()==super.getMonths()&&super.getMonths()<160) { System.out.println("名字"+name+months+"的资为"+(mon*hours+100)); }else if(super.getBirthday()!=super.getMonths()&&super.getMonths()<160) { System.out.println("名字"+name+months+"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 huada; 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 huada; public class Company { public void getsalary(ColaEmployee c, int month) { System.out.println(c.name + c.month + "的工资为" + c.getSalary(month)); } public static void main(String[] args) { ColaEmployee[] c = { new SalariedEmployee("月薪员工", 6, 3500), new HourlyEmployee("时薪员工", 8, 16, 360), new SalesEmployee("销售员工", 9, 188, 30), }; for (int i = 0; i < c.length; i++) { new Company().getsalary(c[i], 5); } } }
