Question

The classes you will write are: Person, UltimatePlayer, Captain, Coach, and UltimateTeam. Detailed below are the requirements for the variables and methods of each class. You may need to add a few additional variables and/or methods; figuring out what is needed is part of your task for this assignment.

Person

Variables

• String firstName - Holds the person's first name.

• String lastName - Holds the person's last name.

Methods

• Person(String firstName, String lastName) - Constructor that takes in String parameters representing the first and last names.

• int throwDisc(int pow) - returns the distance in yards a frisbee is thrown by the person. This is calculated by multiplying the power of the throw by 2. The power is given by the parameter pow, with a minimum value of 1 if pow is below this, and a maximum value of 10 if pow is above this.

• String toString() - Returns a String with the following format: lastName, firstName

Coach extends Person

Variables

• String role - Role of coach on the team. This is a flexible description; there are no required values for this variable. For example, “Head Coach” or “Assistant Coach”.

Methods

• Coach(String firstName, String lastName, String role) - The first and last names should be set by calling the constructor of the parent class.

• String toString() - Returns a two-line String with Coach info formatted as follows:

Wagner, Rebecca
   Role: Head Coach

Note: there are three spaces before "Role: ...".

UltimatePlayer extends Person

Variables

• int jerseyNumber - Using a static variable to keep track of ultimate player jersey numbers, every player should be assigned a unique value for their own jersey number.

• String position - Represents a player’s position. Possible values are “handler” and “cutter”.

Methods

• UltimatePlayer(String firstName, String lastName, String position) - Constructor that accepts the first name, last name and the position of a player. The first and last names should be set by calling the constructor of the parent class. Position should be set to “handler” if the input string is not “handler” or “cutter”. The UltimatePlayer constructor also sets the jersey number to the next available positive integer. The first UltimatePlayer created should have a jersey number of 1, the second will have a jersey number of 2, third of 3, etc.

• String getPosition() - Returns the UltimatePlayer's position.

• int throwDisc(int pow) - returns the distance in yards a frisbee is thrown by the player. This is calculated by multiplying the power of the throw by 4. The power is given by the parameter pow, with a minimum value of 1 if pow is below this, and a maximum value of 10 if pow is above this.

• String toString() - Returns a three-line String with UltimatePlayer information formatted as follows:

Smith, Mary
   Jersey #: 1
   Position: cutter

Note: there are three spaces before "Jersey #: ..." and "Position: ...".

Captain extends UltimatePlayer

Variables

• boolean type - Captains on an Ultimate team are usually responsible for either offense or defense. This variable is a boolean representing the type of captain, true for offense, false for defense.

Methods

• Captain(String firstName, String lastName, String position, boolean type) - The first and last names and the position should be set by calling the constructor of the parent class.

• int throwDisc(int pow) - returns the distance in yards a frisbee is thrown by the person. This is calculated by multiplying the power of the throw by 5. The power is given by the parameter pow, with a minimum value of 1 if pow is below this, and a maximum value of 10 if pow is above this.

• String toString() - Returns a four-line String with Captain info formatted as follows:

Lee, Sarah
   Jersey #: 2
   Position: handler
   Captain: offense

Note: there are three spaces before "Jersey #: ...", "Position: ..." and "Captain: ...".

UltimateTeam

Variables

• ArrayList<UltimatePlayer> players - The list of ultimate players on the team.

• ArrayList<Coach> coaches - A list of the team’s coaches.

Methods

• UltimateTeam(ArrayList<UltimatePlayer> players, ArrayList<Coach> coaches) - A constructor that specifies the coaches and players of the team.

• String getCutters() - Returns a String listing all the UltimateTeams's UltimatePlayers that have the position of “cutter” in the order they appear in the players list. Each String can be produced using the toString method, and should be followed by a line break.
  

• String getHandlers() - Returns a String listing all the UltimateTeams's UltimatePlayers that have the position of “handler” in the order they appear in the players list. Each String can be produced using the toString method, and should be followed by a line break.

• String toString() - Returns a multiline String listing the Coaches and UltimatePlayers on the UltimateTeam. The String is formatted as shown in this example:

COACHES
Mathour, Maryam
   Role: Head Coach
Van Loben Sels, Soren
   Role: Assistant Coach

PLAYERS
Trong, Sammy
   Jersey #: 1
   Position: handler
Patel, Jayant
   Jersey #: 2
   Position: handler
Ozaeta, Myra
   Jersey #: 3
   Position: cutter
Holbrook, Lisa
   Jersey #: 4
   Position: cutter
Kvale, Lisbeth
   Jersey #: 5
   Position: cutter
Henry, Malik
   Jersey #: 6
   Position: handler
   Captain: offense
Pak, Joseph
   Jersey #: 7
   Position: cutter
   Captain: defense

The coaches listing is made up of all items from the coaches ArrayList in order. The players listing is made up of all items from the players ArrayList in order.

Final Notes

Remember, all variables should have an access level of private and all required methods should have an access level of public. Wherever possible, the child class should use a call to the parent's toString and/or constructor methods.

Use the runner class main method to test all your classes, and please don't add a main method to any of the other classes or your code may not be marked correctly.

When debugging your code it makes sense to debug the classes higher in the hierarchy first: for example the methods in the Captain class may not work correctly until the methods in its parent class (UltimatePlayer) work properly. The last thing to debug is the UltimateTeam class, as this relies on methods from all the other classes created.

Milestones

As you work on this assignment, you can use the milestones below to inform your development process:

Milestone 1: Write the Person class, then write the Coach class extending the Person class with all methods implemented.

Milestone 2: Write the UltimatePlayer class extending the Person class with all methods implemented.

Milestone 3: Write the Captain class extending the UltimatePlayer class with all methods implemented.

Milestone 4: Write the UltimateTeam class and implement all the methods it contains.
