Average height method should return average height.

• Create a Netbeans project (or keep developing from your previous lab) with
  • • App.java
  • Model
    • Model.java
    • FootballPlayer.java
    • Height.java
    • Person.java
    • OffensiveLine.java

Functionality

• The application App creates a Model object
• The Model class
  • creates 3 FootballPlayer objects
  • creates an OffensiveLine object using the 3 FootballPlayer objects
  • displays information about the OffensiveLine object and its 3 players
    • it is a requirement that this should be done using the toString( ) method in OffensiveLine, which will use toString( ) in FootballPlayer
  • displays the average height of the OffensiveLine
    • this will be done using the averageHeight in the OffensiveLine

The classes

• App
  • it has the main method which is the method that Java looks for and runs to start any application
  • it creates an object (an instance) of the Model class
• Model
  • this is the class where all the action is going to happen
  • it creates three football players
  • it creates an OffensiveLine object using the three players
  • displays information about the OffensiveLine
    • this has to be done using the OffensiveLine object
    • this is really information about its 3 players
    • the format is free as long as it contains all the information about each of the 3 players
  • displays the average height of the OffensiveLine
    • this has to be done using the OffensiveLine object
    • this has to call the averageHeight method in OffensiveLine

• Person
  • has the following attributes
    • String name;
    • Height height;
    • int weight;
    • String hometown;
    • String highSchool;
  • and a method
    • String toString( )
    • toString( ) overrides the superclass Object toString( ) method
    • toString( ) returns information about this class attributes as a String
  • encapsulation
    • if you want other classes in the same package yo have access to the attributes, you need to make them protected instead of private.

• FootballPlayer

    • int number;
    • String position;
  • and a method

    • toString( ) returns information about this class attributes as a String

• Height
