We cannot do this for public methods.
Also, a tag might be added, @exclude tag
From Docs.
@exclude
For API to be excluded from generation by Javadoc. Programmer would
mark a class, interface, constructor, method or field with @exclude.
Presence of tag would cause API to be excluded from the generated
documentation. Text following tag could explain reason for exclusion,
but would be ignored by Javadoc. (Formerly proposed as @hide, but the
term "hide" is more appropriate for run-time dynamic show/hide
capability.) For more discussion, see: Feature Request #4058216 in
Developer Connection.
