Inheritance

The College Football Playoff (CFP) is the new system in American college football that has determined a national champion for the NCAA Division I Football Bowl Subdivision (FBS) starting in the 2014 season. It replaced the Bowl Championship Series (BCS) previously used that generated much controversy.¹ Unlike the BCS, the new format does not use computer rankings or polls to select the participants. In the playoff four teams play in two semifinal games, with the winners advancing to the new College Football Championship Game. Six bowl games — the Rose Bowl, Sugar Bowl, Orange Bowl, Cotton Bowl, Fiesta Bowl, and Peach Bowl — rotate as hosts for the semifinal games. A committee of 12 members including athletic directors, former coaches, administrators and others vote to select and seed the teams.² See www.collegefootballplayoff.com for more detailed information.

You are to write an application to read the committee votes and select and seed the teams. For the sake of simplicity, the input file will include votes on only 10 teams, with one line per committee member. Since the voting is by secret ballot, the votes of each committee member will be anonymous.

Once the votes have been read, the application will show the rankings of the ten teams, along with their total votes (lower is better). The application will be able to show the detailed votes of each anonymous committee member for each team.

Since the CFP intends to provide weekly rankings as the season progresses, the user will be able to select other voting files and display the results.

Operation

• When the user selects the Read Votes button, the application reads the committee voting file.
• When the user selects the Rank Teams button, the application selects and seeds the teams and displays the output. If the user selects the Rank Teams button again, a new file will be read in and results displayed.
• When the user selects the Show Details button, the application will display the votes of each committee member for each team, listed in ranked order.
• If the user selects Read Votes again, another file can be read in and repeat the displays
• When the user closes the frame or presses the Exit button, the application exits.

Specifications

Data Element – CollegeFootballTeam class

Create a CollegeFootballTeam class that inherits from the Team class (Team.java is supplied). Team.java is a high-level class that would accommodate any team, regardless of sport, professional or amateur. CollegeFootballTeam will also contain instance variables for the team’s conference, the votes for that team, and the sum of votes, and inherit instance variables for the team name, sport, and professional (true/false). It will include a getSumOfVotes method to retrieve the sum of the votes and a getVotes method to retrieve an array of votes, and a setter and a getter for the Conference name. Provide a default no-argument constructor and a three-argument constructor whose arguments are the String name of the team, the String name of the Conference, and an array of integers that will hold the votes for the team.

 

Data Structure – An ArrayList< CollegeFootballTeam > of CollegeFootballTeam objects.

 

Data Manager – CollegeFootballPlayoffManager class

Create a CollegeFootballPlayoffManager class. It will contain an ArrayList< CollegeFootballTeam > of CollegeFootballTeam objects. Data Managers are in charge of adding to the data structure, deleting from the data structure, updating the data structure, retrieving information from the data structure and any other methods that involve the data structure as a whole. This Data Manager will provide methods to read the input file (read Votes) and return an ArrayList< CollegeFootballTeam > of teams in order of their voted ranking (rankTeams). Follow the Javadoc that I gave you for your CollegeFootballPlayoffManager class so that the JUnit test for this class will work correctly. Add any additional methods as required for your design.

 

GUI Driver

• It will contain a CollegeFootballPlayoffManager object.
• Use a JOptionPane at the beginning of the application to prompt the user to choose a file to read.

When the application starts, only the relevant buttons are activated.

Use the JFileChooser class to select a file to read.

• When the user selects the Rank Teams button, display the teams by name in order (#1 through #10).
• When the user selects the Show Details button, display the 10 teams by name and the votes of each (anonymous) committee member.

Data File – The data files will be text files with two header lines and one line per committee member. The first line will contain the team names, and the second line will contain the corresponding conference names. Each subsequent line will be a sequence of 1 through 10, separated by commas. There will be several data files, labeled by week (the actual committee will vote seven times during the season, starting on Oct 28^th.)
