Retrieve only static fields declared in Java class

I have the following class:

public class Test {
public static int a = 0;
public int b = 1;

Is it possible to use reflection to get a list of the static fields only? I'm aware I can get an array of all the fields with
. But it seems there's no way to determine if a
instance represents a static field or not.

You can do it like this:

Field[] declaredFields = String.class.getDeclaredFields();
List<Field> staticFields = new ArrayList<Field>();
for (Field field : declaredFields) {
    if (java.lang.reflect.Modifier.isStatic(field.getModifiers())) {
