java中的年月日简单编程

将这段代码拷贝到UseBirthday类中和你的比较一下看看
public class UseBirthday {
public static void main(String[] args) {
Birthday a=new Birthday(2000,1,1);
a.GetBirthday();
a.Birthday(2008,5,12);
a.GetBirthday();
}
}

class Birthday {
private int Year, Month, Day;
Birthday(){
Year=2000;
Month=1;
Day=1;
}

Birthday(int y,int m,int d) {
Year = y;
Month = m;
Day = d;
}

public void Birthday(int y,int m,int d){
Year = y;
Month = m;
Day = d;
}
int Gety() {
return Year;
}

int Getm() {
return Month;
}

int Getd() {
return Day;
}

void GetBirthday() {
System.out.println(Gety() + "年" + Getm() + "月" + Getd() + "日");
}
}

？？？？？？？？什么问题撒

是啊，没说问题

你那类的初始化或者什么的是不是不合适啊？
public void Brithday(int y,int m,int d)
{
