Assignment 1

Assignment    1
Objectives    
• Practice implementing classes
• Review arrays and Strings
• Practice reading and understanding specifications
• Exposure to more complete testing
Introduction
You are creating a set of classes that can be used in a new “Fantasy Baseball Team”
application. You are creating the infrastructure to allow a user to create their own
Fantasy Baseball Team and add players to that team. In this assignment you will
implement the classes that will be used by a person creating and managing their player
roster.
You will create a Team class, which will store the team name and a list of players
associated with the team. A player will store both a name and a batting average
associated with the player (ie. Jose Bautista’s batting average is 350).
Don’t worry if you know nothing about baseball! This is the great thing about
programming to a specification, you don’t NEED to be an expert in the area, just follow
the spec!
The following UML diagram provides the specification for the three classes involved,
showing the attributes contained in each class and a list of the methods you will need to
implement in each class. The Team class contains a PlayerList object, which is
subsequently made up of Player objects.
Quick    Start
1)Download a1tester.java Player.java PlayerList.java Team.java
2)Read the comments in Player.java and repeat the following until no errors are reported
a) Implement one of the methods in Player.java, PlayerList.java, or Team.java
b) Compile and run the test program a1tester.java
c) If no errors reported by test program see the Grading section of this document
You should implement your solution in this order: Player.java, then
PlayerList.java and finally Team.java.
Understanding    the    test    program:    a1tester.java
a1tester.java will test your implementations of Player, PlayerList and
Team
One of the first things you should do after downloading the source code files is to
compile and run the test program.
Compile the test program by typing:
javac a1tester.java
Run the test program by typing:
java a1tester
You should see the following output:
Player testing.
Failed test: 0 at line 53
The tester is reporting that your implementation is failing the very first test. This is
hardly surprising, since you haven't written any code yet!
There are 31 tests and your goal for the assignment is to pass them all.
More    details    on    what    to    do
You should start working in Player.java
The comments above each method to be implemented provide an unambiguous
description of exactly what the method is to accomplish. Read the comments carefully
before implementing the method.
First, implement the constructor that takes a single parameter:
public Player (String name)
Then implement getName and getBattingAvg.
Now, run the tester, you should have passed tests 0 and 1.
Then implement the second constructor:
public Player (String name, String battingAvg)
Run the tester again and you should have passed tests 2 and 3.
Now implement setName and getName. Run the tester and you should have passed
test 4.
Now implement setBattingAvg and getBattingAvg. Run the tester and you
should have passed test 5.
Now implement the toString method. Run the tester and you should have passed test
6.
Finally, implement the equals method. Remember that we don't consider the
battingAvg when comparing Players, only the name.
Run the tester and you should have passed tests 8 and 9. Congratulations you've
completed about 1/3 of the assignment!
Now move on to PlayerList.java. I suggest you implement the methods in the following
order: constructor, size, add, get, find, and finally remove.
Finally, work on Team.java. This is the easiest to implement, since you will primarily
be calling methods on the instance of PlayerList you allocate in the constructor. You
shouldn't have to write more than a few lines of code in each method.
Submission
Submit your Player.java PlayerList.java and Team.java using conneX.
Please be sure you submit your assignment, not just save a draft.
A reminder that it is OK to talk about your assignment with your classmates, and you are
encouraged to design solutions together, but each student must implement their own
solution.
We will be using plagiarism detection software on your assignment submissions.
Grading
If you submit something that does not compile, you will receive a grade of 0 for the
assignment. It is your responsibility to make sure you submit the correct files.
Requirement Marks
You submit something that compiles 1
1 mark for each test case you pass Up to 31
