Project 1: Sports League Management Program
Objectives
• Familiarize yourself with Files in Java
• Learn to use ArrayLists
• Practice with Strings
Create a program to manage a League
For this program, create a class League that includes the name of the league and a list of all the players in the
league. (ArrayLists will be covered on February 14th but you can also read ahead to zyBook chapter "1.32 Array
Lists".) You will also need to keep track of the number of players in your league. In addition to the getters/setters
for the class, it will also contain the following methods:
1. void addPlayer(Player newPlayer) - This method must be used to add new players to the league. Helpful note: T
his may be a good place to increment the counter for the number of players currently in the league.
2. printleague() - Print a list of all the players in your league. Make sure to use the Player class' toString()
method for this.
3. printAverageScore() - Calculate and print the average of all the players scores in the league.
Player class
The Player class will only contain the name of the player, the name of the team and the number of field goals made
by the player. For this class, you need the constructor, getters/setters, and the toString() method.
League: Driver class
The driver class (LeagueDriver) will contain the main and must contain the following functionality:
• Read in the player information from an external text file. The name of the text file must be passed into the
program through the command line arguments.
• Use a scanner to read in the file and to obtain the name, team name, and total field goals made for each player
• Use a scanner to read in the file and to obtain the name, team name, and total field goals made for each player
in the file.
Invoke the printLeague() method to print a list of all the players in that league.
• Invoke the printAverageScore() method to display the average field goals made for the whole league.
Reading the Player information from a file
• Create a list of players (name, team, field goals) in a file on your computer. This file will be created as a
separate text file in a text editor such as Sublime. For example, you may create a file (Players.txt) that contains
the following:
Steph Curry, Golden State Warriors, 498,
LeBron James, Cleveland Cavaliers, 484,
Russell Westbrook, Oklahoma City Thunder, 459,
