Lab 3 Solution

PROGRAM SPECIFICATIONS




In this assignment you will start building the basis for a football team. Your team will be contained in an ArrayList. The information for a team will come from multiple files specified by reading the contents of the directory.




CLASS SPECIFICATIONS




Position




Values, kicker, quarterback, runningback, tightend, widereceiver




toString returns K, QB, RB, TE, WR













Player




A Player class contains the following attributes as private instance fields:




First Name – String



Last Name – String
Team Name – String
Position Type – Position Enum
Games Played - int



The class should have the following instance behaviors:




An explicit value constructor (passed the above instance fields)



A toString (returns a String formatted as follows:
Name: first last

Team: the team name

Position: the position

Games Played: the number




A compareTo method that compares by Games Played, Team Name, Last Name, First
Name

Accessor (get) methods for each field *as you deem necessary*



Modifier (set) methods for each field *as you deem necessary*
Helper methods *as you deem necessary*
CSCD211Lab3Methods




readDirectoryName(kb) – Prompts the user to enter a directory name. Ensures the name entered is a directory if not reprompts. Once a valid directory name is obtained a File object is returned containing the directory name.



readDirectoryContents(dirName) – Using the passed in file object this methods returns an array of file objects representing the files within the directory.



readPlayers(inFileNames) – reads in the information from the file creates and array list and inserts the player into the array list. When all files have been processed the array list is returned. The list will be trimmed to size after the operation is complete.



menu(kb) – valid menu choices are below. You must ensure the number is within range.



Print all Players to the screen



Print all Players to the User Specified file
Sort the Players by ìNatural Orderî
Sort the Players by Team and print to the screen
Sort the Players by Position and print to the screen
Remove a player
Print a entire team and only that team to a user specified file
Quit



printList(myPlayers, System.out) – Prints the list one player at a time with a carriage return separating each player.



readFileName(kb) – reads and returns a string representing the name of the output file



printList(myPlayers, fout) - Prints the list one player at a time with a carriage return separating each player.



removePlayer(myPlayers, kb) – prompts the user for player information. Searches the list for that player and removes the player from the array list. The list will be trimmed to size after the operation is complete. If no player can be found the appropriate message will be displayed and the list will remain unchanged.






printTeamPlayers(myPlayers, kb) – prompts the user for the 3 letter team code and prints all the players from that team - one player at a time with a carriage return separating each player.









INPUT FILE SPECIFICATIONS




The position type will be derived from the csv file name. The input file will have at least one entry. Each player type is specified as a CSV file. Sample input files are provided.

OTHER SPECIFICATIONS




You must validate all ranges



Your ArrayList will always be of the correct size. (trimToSize)
Since we are using ArrayLists we use Collections instead of Arrays. The second argument is still a class that implements a Comparator.



o Collections.sort(myPlayers, new TeamSort());




o Collections.sort(myPlayers, new PositionSort());










TO TURN IN




There are multiple turn ins for this lab.




Your stubbed out methods ensuring all code compiles will be submitted via git commit to your repository on GitHub. This is required within by 11 PM on (See Date Specified in Canvas).



A zip file, in Canvas, by the required due date containing:



all java files
all input file(s) used to test your program program
all output file(s)
a test run named cscd211lab3out.txt – testing all aspects



We should be able to download the zip and compile your code, and then run your code.
Name your zip, your last name first letter of your first name lab3.zip (Example: steinerslab3.zip)
