15-127 section B

Competency Exam 15-111/200

Assignment

Professional golf tournaments are generally played over four days. After the first two days, a score is determined that is called "the cut". "The cut" is a score that is used to decide which players go into the final two rounds: players with total scores less than or equal to the cut advance to the final round. Players whose score is greater than the cut are eliminated.

Example:

Cut: 145

Tiger Woods 70 69

Greg Norman 71 76

In this case Tiger Woods advances to the final two rounds (70 + 69 is less than 145), but Greg Norman wouldn’t (71 + 76 is greater than 145).

You will be implementing one method for a golf tournament:

1) A method of the LinkedList class, sort(), that will sort the list from

lowest to highest, according to compareTo()

Project files

Player.java has been fully implemented, and it contains scoring details for a golf player. Each player has a first name, a last name, a series of integers representing his scores in two rounds of golf, and a total (cumulative) score. The total score is simply the addition of all the scores. For example, if one player scores 73 and 72, then his total score is 145.

LinkedList.java is a class that implements a linked list, which is the basis of the PlayersDB data base. All is implemented except the sort() method which you must implement. This method sorts items in the list, form lowest to highest, according to compareTo().

PlayersDB.java is a class that implements a database (LinkedList) of objects of another class called Player. It is implement for you. It will print out the scores of each player, as they were read from the file. It will then call your new LinkedList sort() to put the players in order, and the print the list again – this time in order.

Sample output

There are two input files that could be used with your class: golf1.txt and golf2.txt. Make sure you test your solution with both input files.

Sample output for both input files:

<golf1.txt>

Enter the name of the file: golf1.txt

File golf1.txt has been opened.
