Java - Reflection: Get fields belonging to current class only

Question

How can I get the fields associated only with the current class instead of all of its parent classes as well?

public class BaseClass()
{
     public int x = 0;
}

public class AnotherClass() extends BaseClass
{
     public int y = -1;
     public int z = -2;

     public void doStuff()
     {
          for(Field f : this.getClass().getFields())
          {
              //Save each field to a file
          }
     }
}

I want to get only Y and Z, which belong to AnotherClass. But the above gives me X as well.

This is meant to replace having to type each value that I want to save. It's not being saved in any typical format. It must be saved like this so don't suggest saving the fields in a different way.

Filtering out each field's name would defeat the purpose of this as there are well over 200.

Answer 1

You can get only the fields declared in the class with getDeclaredFields. It will exclude inherited fields.

Answer 2

You can filter based upon the Field's getDeclaredClass():

public static List<Field> fieldsDeclaredDirectlyIn(Class<?> c) {
    final List<Field> l = new ArrayList<Field>();
    for (Field f : c.getFields())
        if (f.getDeclaringClass().equals(c))
            l.add(f);
    return l;
}

This picks just y and z for your example.
