            this.name = name;
            this.month = month;

            this.monSalary = monSalary;
        }
        public double getSalary(int month){
            if(super.month==month){
                return monSalary+100;
            }else{

            this.hourSalary = hourSalary;
            this.hourNum = hourNum;
        }
        public double getSalary(int month){
        if(super.month==month){
            if(hourNum>160){

            super(name,month);
            this.monthSales = monthSales;

            }
        }

}

(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。

public class Company {
     public void getSalary(ColaEmployee a,int month){
            System.out.println(a.name+"在"+month+"月的月薪为"+a.getSalary(month)+"元");
        }
}
public class TestCompany {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        ColaEmployee[] ae1={
                new SalariedEmployee("SalariedEmployee",5,8000),
                new HourlyEmployee("hourlyEmplotee",5,60,250),
                new SalesEmployee("salesEmployee",4,60000,0.4)
        };
        for(int i=0;i<ae1.length;i++){
            new Company().getSalary(ae1[i],5);
        }
    }

}
