Re: Using arrays of objects ?

java.util.Collection and friends make this pretty easy.

I could keep a reference to each tool object as added in an array of type
tool but an array is declared with a fixed length, so short of defining the
array to have a some arbitrary large size I can't see how to deal with this
list of objects. I don't want to use a database at this time.

ArrayList<Tool> is the most common way to do this. Depending on your needs,
you may prefer a HashSet, TreeSet, LinkedList, or some other Collection that
fits your performance and usage requirements.
