Vertex Class field question

[Han Gao]

Hi in my Vertex class, I have a linkedList field for the
implementation of ajacency list. The problem with that is
in my ajacency matrix implementation, this field is completely
useless. I wonder if that's okay or the linkedLists should
be implemented in the AdjListGraph instead (maybe gets associated with
the vertex by a hashmap or so )? Thanks.

You may want to rethink how you are sharing classes between the
implementations. The approach you describe is rather inelegant. Do you
need a vertex class for both impls? If so, does it need to be the same?
If not, why force yourself to use it?
