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。
1 public class ColaEmployee { 2 String name; 3 int bmonth; 4 public void getSalary(int month) { 5 System.out.println("月份:"+month); 6 } 7 }
1 public class Company { 2 public void method(ColaEmployee a) { 3 if(a instanceof HourlyEmployee) { 4 HourlyEmployee H =(HourlyEmployee)a; 5 H.hsal("张三",45,175,6,6); 6 }else if(a instanceof SalariedEmployee) { 7 SalariedEmployee c=(SalariedEmployee)a; 8 c.getsal("李四",7,7,1000); 9 }else if(a instanceof SalesEmployee) { 10 SalesEmployee b = (SalesEmployee)a; 11 b.xiaoshouSalar("王五",2000,3,5,6); 12 } 13 } 14 }
1 public class HourlyEmployee extends ColaEmployee{ 2 public void hsal(String name ,int hoursal,int mhour,int bmonth, int month){ 3 if(month==bmonth) { 4 if(mhour<=160 && mhour>0) { 5 System.out.println(name+"工资是"+(hoursal*mhour)+100); 6 }else { 7 System.out.println(name+"工资是"+(((mhour-160)*hoursal+(hoursal*160))+100)); 8 } 9 }else { 10 if(mhour<=160 && mhour>0) { 11 System.out.println(name+"工资是"+(hoursal*mhour)); 12 }else { 13 System.out.println(name+"工资是"+(((mhour-160)*hoursal+(hoursal*160)))); 14 } 15 } 16 } 17 }
public class SalariedEmployee extends ColaEmployee{ 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); } } }
1 public class SalesEmployee extends ColaEmployee { 2 int monthxiaoshou; 3 int tichenglv; 4 public void xiaoshouSalar(String name,int mxiaoshou,int tichenglv,int bmonth,int month) { 5 if(month==bmonth) { 6 System.out.println(name+"工资是"+(mxiaoshou*(1+tichenglv)+100)); 7 }else { 8 System.out.println(name+"工资是"+(mxiaoshou*(1+tichenglv))); 9 } 10 } 11 }
public class TestCompany { public static void main(String[] args) { 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); } }
