关于一个程序问题 清高手帮忙看一下

[wanglukai]

import java.util.*;
class Employee{
public Employee(String n,double s,int year, int month,int day){
name=n;
salary=s;
GregorianCalendar calendar=new GregorianCalendar(year,month-1,day);
hireday=calendar.getTime();
}
public String getName(){
return name;
}
public double getSalary(){
return salary;
}
public Date getHireday(){
return gethireday;
}
private String name;
private double salary;
private Date hireday;
}

class Manage extends Employee{
public Manage (String n,double s,int year,int month,int day){
super(n,s,year,month,day);
bool=0;
}
public double getSalary(){
double basesalary=super.getSalary();
return basesalary+bool;}

public void setBool(double b){
bool=b;
}
private double bool;}
public class Salary{
public static void main(String[] args){
Manage boss=new Manage("sgfd",5000,1985,5,12);
boss.setBool(500);

Employee[] staff=new Employee[3];
staff[0]=boss;
staff[1]=new Employee("zhang",5000,1998,5,15);
staff[2]=new Employee("li",4500,1985,5,23);

for(int i=0;i<3;i++)
{
Employee e=staff[i];
System.out.println(e.getName()+e.getSalary()+e.getHireday());
}

}
}



错误提示：

public Date getHireday(){
return gethireday;
}
要返回的什么东西？！！

[hl_longman]

public Date getHireday(){
return hireday;
}


OK!
这是JAVA核心技术上的例子吧?

[andy_zhang_ping]

public Date getHireday(){
return hireday;
}
返回的租用时间吧！

[xue_1205]

public Date getHireday(){
return hireday;
}
应该是这个吧，这好象是Ｃｏｒｅ　ｊａｖａ　２中的例子

[Frank1982]

gethireday这个变量没有定义啊
敲错了吧
应该是hireday

[panzhiwei]

public Date getHireday(){
return gethireday; 改为return hiready
}

[lixiang823517]

return hireday;
