COPY AND PASTE THE CODE BELOW

Assignment Objectives

1.Practice on implementing interfaces in Java

FootballPlayer will implement the interface TableMember

2.Overriding methods

when FootballPlayer implements TableMember, FootballPlayer will have to write the real Java code for all the interface abstract methods

Deliverables

A zipped Java project according to the How to submit Labs and Assignments guide.

O.O. Requirements (these items will be part of your grade)

1.One class, one file. Don't create multiple classes in the same .java file

2.Don't use static variables and methods

3.Encapsulation: make sure you protect your class variables and provide access to them through get and set methods

4.All the classes are required to have a constructor that receives all the attributes as parameters and update the attributes accordingly

5.All the classes are required to have an "empty" constructor that receives no parameters but updates all the attributes as needed

6.Follow Horstmann's Java Language Coding Guidelines

7.Organized in packages (MVC - Model - View Controller)

These are the four methods that Football Player has to Implement public String getAttribute(int). Returns the value of a specific attribute the input peronter start with a for the first attribute, then I for the second attr bute and so on public ArrayList String getAttributes: Returns the value of all ottributes os on ArrayList of Strings - public String getAttributeName(int n). Neturns the name of a specific attribute. The input parameter start with o for the first attribute, then 1 for the second stri ute and son public ArrayList-String getAttributions: Returns the name of all attributes o an ArrayList of Strings the abstract sheds are You are building an application to display data in the form of a table.
