Well, if you are indeed interested in storing arrays in the Vector, consider
using List collection ( ArrayList, and in fact Vector itself ) instead
of arrays. The List subclasses override the "equals" method of Object.
Indeed they override the hashcode also sensibly - the hashcode
of a List is a function of the hashcode of its elements. I dont recall
what the "contains" method of Vector does exactly, but potential speed ups
in terms of rejection tests could be achieved by first comparing
hashcodes....Just a thought...
