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 kkk; public class lll{ String name; int bmonth; public void getSalary(int month) { System.out.println("月份:"+month); } } package kkk; public class lll { public void method(ColaEmployee a) { if(a instanceof HourlyEmployee) { HourlyEmployee H =(HourlyEmployee)a; H.hsal("张三",45,175,6,6); }else if(a instanceof SalariedEmployee) { SalariedEmployee c=(SalariedEmployee)a; c.getsal("李四",7,7,1000); }else if(a instanceof SalesEmployee) { SalesEmployee b = (SalesEmployee)a; b.xiaoshouSalar("王五",2000,3,5,6); } } } package kkk; public class HourlyEmployee extends lll{ public void hsal(String name ,int hoursal,int mhour,int bmonth, int month){ if(month==bmonth) { if(mhour<=160 && mhour>0) { System.out.println(name+"工资是"+(hoursal*mhour)+100); }else { System.out.println(name+"工资是"+(((mhour-160)*hoursal+(hoursal*160))+100)); } }else { if(mhour<=160 && mhour>0) { System.out.println(name+"工资是"+(hoursal*mhour)); }else { System.out.println(name+"工资是"+(((mhour-160)*hoursal+(hoursal*160)))); } } } } package kkk; public class SalariedEmployee extends lll{ int mmoney; public void getsal(String name,int month,int bmonth, int mmoney) { if(month==bmonth) { System.out.println(name+"工资是:"+(mmoney+100)); }else { System.out.println(name+"工资是:"+mmoney); } } } package kkk; public class SalesEmployee extends lll { int monthxiaoshou; int tichenglv; public void xiaoshouSalar(String name,int mxiaoshou,int tichenglv,int bmonth,int month) { if(month==bmonth) { System.out.println(name+"工资是"+(mxiaoshou*(1+tichenglv)+100)); }else { System.out.println(name+"工资是"+(mxiaoshou*(1+tichenglv))); } } } package kkk; public class lll { public static void main(String[] args) { // TODO Auto-generated method stub Company C = new Company(); HourlyEmployee c= new HourlyEmployee(); C.method(c); SalariedEmployee b = new SalariedEmployee(); C.method(b); SalesEmployee a = new SalesEmployee(); C.method(a); } }
