Ok so if I do.
addElement("mybold",new B());
It's not an integer anymore and I have to check instanceof so i can do a
comparison. The whole reason we use a hashtable instead of a vector is so that we
dont have to remember the order in which we inserted elements so we can access
anyelement that has been inserted as long as we know the name, I use
Integer.toString(Object.getHashCode()) more for convience so that I don't force
everyone to name their elements.
