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 sg; 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 month; } }
package sg; public class SalariedEmployee extends ColaEmployee{ double monthsalary ; public SalariedEmployee() { super(); } public SalariedEmployee(String name, int mouth ,double monthsalary) { super(name, mouth); this.monthsalary = monthsalary; } @Override public double getSalary(int month) { if (super.month == month) { return monthsalary + 100; } else { return monthsalary; } } }
package sg; public class HourlyEmployee extends ColaEmployee{ int hourSalary; int hour; public HourlyEmployee() { super(); } public HourlyEmployee(String name, int month, int hourSalary, int hour) { super(name, month); this.hourSalary = hourSalary; this.hour = hour; } @Override public double getSalary(int month) { if(super.month == month){ if (hour > 160) { return hourSalary * 160+ (hour-160)*1.5*hourSalary + 100; }else { return hourSalary * hour + 100; } }else{ if (hour > 160) { return hourSalary * 160 +(hour - 160)*1.5*hourSalary ; }else { return hourSalary * hour; } } } }
package sg; public class SalesEmployee extends ColaEmployee{ double monthsalary; double monthcommission ; public SalesEmployee(String string, int i, int j, double d) { super(); } public SalesEmployee(String name,int month,double monthsalary, double monthcommission) { super(name,month); this.monthsalary = monthsalary; this.monthcommission = monthcommission; } @Override public double getSalary(int month) { if (super.month == month) { return monthsalary*monthcommission + 100; } else { return monthsalary*monthcommission; } } }
package sg; public class Company { public void getSalary(ColaEmployee c, int month) { System.out.println(c.name + "在" + month + "月的月薪是:" + c.getSalary(month) + "元"); } }
package sg; public class TestCompany { public static void main(String[] args) { ColaEmployee[] cel = { new SalariedEmployee("拿固定工资的员工", 1, 8500), new HourlyEmployee("按小时拿工资的员工", 2, 100,85), new SalesEmployee("销售人员", 3, 70000, 0.1) }; for (int i = 0; i < cel.length; i++) { new Company().getSalary(cel[i],3); } } }
