code: public static FieldJavadoc getJavadoc(Field field) {
          ClassJavadoc javadoc = getJavadoc(field.getDeclaringClass());
          return findFieldJavadoc(javadoc.getFields(), field.getName());
      }
docs: Gets the Javadoc of the given field.
  <p>
  The return value is always non-null. If no Javadoc is available, the returned object's
  {@link BaseJavadoc#isEmpty isEmpty()} method will return {@code true}.
  <p>
  Implementation note: this method first retrieves the Javadoc of the class, and then matches the field name
  with the correct documentation. If the client code's purpose is to loop through all fields doc, prefer using
  {@link #getJavadoc(Class)} (or one of its overloads), and calling {@link ClassJavadoc#getFields()} on the
  returned class doc to retrieve field docs.
  
  @param field the field whose Javadoc you want to retrieve
  @return the given field's Javadoc
