Can I print all fields within a parent class ?

[liangpengfei]

public abstract class FridaParent {
    public int a;
}

public class FridaChild extends FridaParent{
    public int b;
}

FridaChild child = new FridaChild();
child.b = 2;
child.a = 1;

I can print FridaChild instance, but only get filed b's value, I want to get filed a's value as well. Is objection support this?
