Overriding inherited annotations

Question

Hi,
I wish to use the “ParameterPriority” annotation to determine the order of the fields appearance when displaying these objects in a GUI.
Both B and C classes extends class A. If B and C wish to change the appearance order of class A fields, is there a way to override class A annotation values? (or is there another way to obtain this functionality via annotations?)
Bellow you can find a very stupid example for the situation I've described.
Thanks!
// annotation definition:
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.FIELD})
public @interface ParameterPriority {
      int rank();
//class A
Public class A {
@ ParameterPriority (rank=1)
    private String name;
@ ParameterPriority (rank=2)
    private int age;
//class B
Public class B extends A {
@ ParameterPriority (rank=3)
    private boolean isFemale;
//class C
Public class C extends A {
@ ParameterPriority (rank=3)
    private Boolean isStudent;
}

I don't thik you can achieve that on fields (though you should confirm with someone more knowledgeable) because fields cannot be overriden. A sensible workaround would be to annotate field getters rather than the fields themselves: when you override a method, you have the opportunity override its annotations. Another side advantage is that you annotate public things so they will be visible in the javadoc for instance.
Btw, if you rename your annotation method from "rank" to "value", you're allowed to omit the method name:
// annotation definition:
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.METHOD})
public @interface ParameterPriority {
      int value();
//class A
public class A {
    private String name;
    private int age;
    @ParameterPriority(5)
    public String getName() { return name; }
    @ParameterPriority(10)
    public int getAge() { return age; }
public class B extends A {
    @Override
    @ParameterPriority(2)
    public int getAge() { return super.getAge(); }
    // instanceOfA.getMethod("getAge").getAnnotation(ParameterPriority.class).value() == 10
    // instanceOfC.getMethod("getAge").getAnnotation(ParameterPriority.class).value() == 2
