找测试程序的错误 java

package charper9;
public class Test1{
public static void main(String[] args){
Staff staff1=new Staff("Tom","湖南长沙","07315623456","12345@qq.com","长沙理工大学",2475);
System.out.println(staff1.toString());
Person staff2=new Staff("Kate","山东济南","05315623456","12345@qq.com","空军部队",1563);
System.out.println(staff2.toString());
System.out.println(staff2.getStaffId());//是否会出错？
System.out.println(staff2.getCompany());//是否会出错？
System.out.println(staff2.getName());//是否会出错？
Employee staff3=new Staff("Kate","山东济南","05315623456","12345@qq.com","空军部队",1563);
System.out.println(staff3.toString());//调用的是哪个类的toString()方法？
System.out.println(staff3.getStaffId());//是否会出错？
System.out.println(staff3.getCompany());//是否会出错？
System.out.println(staff3.getName());//是否会出错？
}
}

Answer 1

你写的类型是不是有问题了

追问

可能，我不知道，刚学

追答

奥！
你看看这两个有什么区别了
Employee staff3=new Staff("Kate","山东济南","05315623456","12345@qq.com","空军部队",1563);
Person staff2=new Staff("Kate","山东济南","05315623456","12345@qq.com","空军部队",1563);
都是采用的多态吗？他们的内容是一样的！！

Answer 2

很简单的一个创建类，并输出一些语句进行比较啊，
你的staff 又没给出来，怎么看啊？！
