4.5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 test; 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; } } package test; 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; } } } package test; public class HourlyEmployee extends ColaEmployee{ private int hourSalary; private int hourNum; public HourlyEmployee(String name, int month,int hourSalary,int hourNum) { super(name,month); this.hourSalary=hourSalary; this.hourNum=hourNum; } public double getSalary(int month) { if(super.month==month) { if (hourNum>160) { return hourSalary*160+hourSalary*(hourNum-160)*1.5+100; }else { return hourSalary*hourNum+100; } }else { if (hourNum>160) { return hourSalary*160+hourSalary*(hourNum-160)*1.5; }else { return hourSalary*hourNum; } } } } package test; 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; } } } package test; public class Company { public void getSalary(ColaEmployee c,int month) { System.out.println(c.name + "在" + month + "月的月薪为" + c.getSalary(month)+"元"); } } package test; public class TestCompany { public static void main(String[] args) { // TODO Auto-generated method stub ColaEmployee[] cel = { new SalariedEmployee("拿固定工资的员工", 6, 54000), new HourlyEmployee("按小时拿工资的员工", 5, 100, 300), new SalesEmployee("销售人员", 3, 6000000, 0.4) }; for (int i = 0; i < cel.length; i++) { new Company().getSalary(cel[i],6); } } }
