“Based on Irkwz's answer” and similarly pointless. You are not checking the values of the fields but only if the array of Field instances returned by getDeclaredFields() contains null , which is always false . You’d have to actually get() the field’s value before checking. And when accessing private fields, you should use SomeClass.class instead of getClass() , because getClass() may return a subclass.
