I don't know what this is doing here, or why you would possible want to do what your trying to do, but anyway...

To successfully store and retrieve objects from a hashtable, the objects used as keys must implement the hashCode method and the equals method.

The below code works, (and, I'll never confess to writing it)

It is sorta covered in the JavaRanch Style Guide.
