计算公司员工的工资(面向对象复习)
某公司的雇员分为以下若干类:
Employee: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:double 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。
SalariedEmployee:Employee的子类,拿固定工资的员工。属性:月薪
HourlyEmployee:Employee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
SalesEmployee:Employee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
BasePlusSalesEmployee:SalesEmployee的子类,有固定底薪的销售人员,工资由底薪加上销售提成部分。属性:底薪。
写一个程序,把若干各种类型的员工放在一个Employee数组里,写一个方法,打印出某月每个员工的工资数额。
注意:要求把每个类都做成完全封装,不允许非私有化属性。
import java.util.Calendar; public class Employee {

} /**

public static double getSalary(int month){
//获取当前月份,属于工具类中的内容
Calendar ca=Calendar.getInstance();
int m=ca.get(Calendar.MONTH)+1;
if(month==m){
return 100;

}
}
}
//固定月薪 public class SalariedEmployee extends Employee { private double monthsalary;//月薪 public SalariedEmployee(){ } public SalariedEmployee(String name,int month){ super(name,month); } public double getMonthsalary() { return monthsalary; } public void setMonthsalary(double monthsalary) { this.monthsalary = monthsalary; } /** * 计算固定月薪员工的工资 * @param monthsalary * @param month * @return 固定月薪员工的工资 */ public double getmonth(double monthsalary,int month){ double n=monthsalary+Employee.getSalary( month); return n; }

//时薪*小时 超过160小时,超过部分1.5工资 public class HourlyEmployee extends Employee{ private double hourlyWage;//时薪 private int hour;//总时长 public HourlyEmployee(){ } public HourlyEmployee(String name,int month){ super(name,month); } public double getHourlyWage() { return hourlyWage; } public void setHourlyWage(double hourlyWage) { this.hourlyWage = hourlyWage; } public int getHour() { return hour; } public void setHour(int hour) { this.hour = hour; } /** * 计算时薪员工的工资 * @param hour * @param hourlyWage * @param month * @return 时薪员工的工资 */ public double gethour(int hour,double hourlyWage,int month){ double n; if(hour>160){ n=160*hourlyWage+(hour-160)*hourlyWage*1.5+Employee.getSalary(month); }else{ n=hour*hourlyWage+Employee.getSalary(month); } return n; } }
//销售额*提成率 public class SalesEmployee extends Employee{ private int salesVolume;//销售额 private double royalty;//提成率 public SalesEmployee(){ } public SalesEmployee(String name,int month){ super(name,month); } public int getSalesVolume() { return salesVolume; } public void setSalesVolume(int salesVolume) { this.salesVolume = salesVolume; } public double getRoyalty() { return royalty; } public void setRoyalty(double royalty) { this.royalty = royalty; } /** * 计算提成 * @param salesVolume * @param royalty * @return 提成 */ public double getroyalty(int salesVolume,double royalty){ return salesVolume*royalty; } }
//销售额*提成+底薪 public class BasePlusSalesEmployee extends SalesEmployee{ private double baseSalary;//底薪 public BasePlusSalesEmployee(){ } public BasePlusSalesEmployee(String name,int month){ super(name,month); } public double getBaseSalary() { return baseSalary; } public void setBaseSalary(double baseSalary) { this.baseSalary = baseSalary; } /** * 计算销售人员的工资 * @param salesVolume * @param royalty * @param baseSalary * @param month * @return 销售人员月薪 */ public double getroyalty(int salesVolume,double royalty,double baseSalary,int month){ return salesVolume*royalty+baseSalary+Employee.getSalary(month); } }
public class EmployeeTest {
public static void main(String[] args){
SalariedEmployee a=new SalariedEmployee("月薪人",7);
HourlyEmployee b=new HourlyEmployee("时薪人",10);
BasePlusSalesEmployee c=new BasePlusSalesEmployee("提成人",1);
System.out.println( a.getName()+":\n月薪"+a.getmonth(10000,a.getMonth()));
System.out.println(b.getName()+":\n月薪"+b.gethour(170,20,b.getMonth()));
System.out.println(c.getName()+":\n月薪"+c.getroyalty(100,50,1000,c.getMonth())); }
}
运行结果:
月薪人:
月薪10100.0
时薪人:
月薪3500.0
提成人:
月薪6000.0
