Answer 1

You have to use reflection to get all the member fields of User class, iterate through them and find their annotations

something like this:

public void getAnnotations(Class clazz){
    for(Field field : clazz.getDeclaredFields()){
        Class type = field.getType();
        String name = field.getName();
        field.getDeclaredAnnotations(); //do something to these
    }
}
