I was hoping someone might be able to point me in the right direction
on how to do the following.

As part  of an assignment  on Hashmaps and Inheritance, I need to read
data from a text  file for a hotel, tokenize  it and put  it into a
hashmap and depending on the number  of tokens 10 or 12 treat them as
either
business guests or travelling guests each of which are subclasses of
the superclass guest.
