关于继承和多态的简单练习

package work07_4; public class HourlyEmployee extends ColaEmployee { //按小时拿工资的员工； double pertime;//每月工作的小时数 double persalary;//每个小时的工资 HourlyEmployee(){} HourlyEmployee(double pertime,double persalary){ super(name,birthday); this.pertime=pertime; this.persalary=persalary; } public void getSalary(int month){ if(month==birthday){ double b=0; if (pertime>160){ b=160*persalary+(pertime-160)*1.5*persalary+100; System.out.println("本月该HourlyEmployee员工的工资为"+b); }else{ b=pertime*persalary+100; System.out.println("本月该HourlyEmployee员工的工资为"+b); } }else{ double b=0; if (pertime>160){ b=160*persalary+(pertime-160)*1.5*persalary; System.out.println("本月该HourlyEmployee员工的工资为"+b); }else{ b=pertime*persalary; System.out.println("本月该HourlyEmployee员工的工资为"+b); } } } }
