Thread: How to access derived class field values?

Hi there.
I want to access derived class field values. I can access field names with my code but for the values Its necessary to create a class instance.
I don't know how to do. look at my code:

for (Field f : getClass().getDeclaredFields()){
	fieldNames += f.getName()+",";
}

How to access values?

public class a{

}
public class b extends a{
  public string name;
}
public class c extends a{
  public string f1;
  public string f2;
}

By that I mean that if the child class did not exist then the parent class should be able to compile and execute. If you think you need the parent class to have access to instances of the child class then you have a bad design.

No man! it's the best idea which I've implemented in dot net.
In dot net I can do this, I just want to know how to do it in Java.

That's one of the better quotes I've heard! Thanks for brightening my day, even though it may have left me a tiny bit sadder (but just for you).
