In order to build a stronger understand of utilization of classes, we will create a Race Results. First people must register for the race. Secondly, during the race day, the data created when they registered comes into play and is used with other classes to record time and lastly to post results. A main class will call these as needed.

We will build a registration system for runners: First Name, Last Name, Age, Gender, City State. We do not care about their payment method.

We will append new users to the altered file.

At day of race people will check in and receive a bib with a number, that number will be associated with them as a racer. Here you will take the registered users and assign a bib.

The race starts and all time is starts.

As people finish, updates to the bib profile are updated. At some point all racers either finish the race or abandon the race. Here you can use random numbers to assign times to people with in ranges.

Results will be computed and posted as the file appears. (aggregate results, build ranting, and post results)

The file represents the end state what the business person want to see at the end. They care about the steps and what questions get asked, but there passion is to hold a race and pose the winners. Getting them to back up and supply the details to create it all, well that is a completely different story.

Include in your project a javadoc.
