Question

Project name: Practical1LastFirst

You are being asked to create a program related to tracking players on a ringette team. It is important to create as per the requirements document. The details of the RingettePlayer class are provided in the following class diagram.

RingettePlayer

-firstName: String -lastName: String -allergies: String -jerseyNumber: int -birthYear: int

Constructors +RingettePlayer()     +RingettePlayer(String, String) +RingettePlayer(int) +RingettePlayer(String, String, String, int)    +getters/setters for all +getInformation():void +display():void +toString(): String

Default Values for Attributes

When values are not provided for attributes, the following are the values that should be set for the attributes. Note that these are the only attributes that are to be in the class.

• firstName and lastName default: “Unknown”
• allergies default: “”
  • The default for allergies is an empty string
• jerseyNumber and birthYear: 0

Constructor Details

Create four constructors in the RingettePlayer class based on the following requirements.

• Default no-parameter constructor
  • Create a default no-parameter constructor for the RingettePlayer which sets attributes to their default values.
• RingettePlayer(String, String)   
  • First and last names passed as parameters and set.
  • the jersey number, birthYear and allergies set to their default values
• RingettePlayer(int)
  • jerseyNumber passed as a parameter
  • Other attributes are set to their default values
• RingettePlayer(String, String, String int, int)
  • Values for all attributes are passed in as parameters and used to set object attribute values.

Controller Class Functionality

In the main method create three object based on the following specifications. You can use your own name for the variable name.

• The first object created should be created using the constructor that accepts two Strings to set the first and last name in the instance (example: “Brielle”, “Jones”). The user does not have to be prompted for these values. They are to be set as hard coded values.

• The second object created should be created with the default constructor and the setters used to set her first name (“Marley”), last name (“Stephens”), allergies (“Dust”) and jersey number (9). The user does not have to be prompted for these values. They are to be set as hard coded values.
• The third object should be created using the default constructor. The values for this object are to be obtained from the user by using the getInformation() method. The output below shows an example with user entered data.
  • Note that when the program runs, they would be prompted for the values of this object as the first interaction with the user.

Additional Requirements

• After creating each of these objects in the main method, have the program display their values to the console.

Ringette Players Name: Brielle Jones Jersey Number: 0 Allergies: Birth Year: 0 Name: Marley Stephens Jersey Number: 9 Allergies: Dust Birth Year: 0 Name: Sarah Miles Jersey Number: 15 Allergies: Nuts Birth Year: 2009

• After showing each of the players above have an additional output which shows the allergies only.

Allergies for all players: Dust Nuts

Answer 1

please find the below classes for the solution:
