You will be implementing the Strategy Design Pattern to create Football Players and have them run plays.

Players:

• QuarterBack, Receiver, and Lineman
• Inherit from Abstract Base Class Player
• Each have a unique toString, that includes the players name
• Each character has a OffenceBehavior and a DefenceBehavior, which is set in the constructor
• They can call setOffenceBehavior and change their offenceBehavior
• They can call setDefenceBehavior and change their defenceBehavior

QuarterBack:

• setOffenceBehavior will randomly choose between setting the behavior to a RunBehavior and a PassBehavior
• setDefenceBheavior will set the defenceBehavior to null

Receiver:

• setOffenceBehavior will set the offenceBehavior to a new ReceiverBehavior
• setDefenceBehavior will set the defenceBehavior to null

LineMan:

• setOffenceBehavior will set the offenceBehavior to OBlockBehavior
• setDefenceBehavior will randomly choose between between Block, Strip, and Sack Behavior

DefenceBehavior

• An interface with one method: play
• Each child implements the interface, and returns a unique message in their play method.

BlockBehavior:

• returns "block a {kick, punt, pass, or catch}", where one of the moves are picked randomly

StripBehavior:

• returns "Strip a ball from runners hands"

SackBehavior:

• returns "Sack the quarterback"

OffenceBehavior

• An interface with one method: play
• Each child implements the interface, and returns a unique message in their play method.

OBlockBehavior:

• returns "block defenders"

RunBehavior:

• returns "runs a {drive (up the gut), draw, pitch, reverse}" -> randomly picking one move

PassBehavior:

• returns "throws a {slant route, out route, seem route, screen pass, hail mary}" -> randomly picking one move

ReceiveBehavior:

• returns "runs a {slant route, out route, seem route, screen pass, hail mary}" -> randomly picking one move

Driver.java

package strategydesignpattern;

public class Football {

public Football() {}

public void play() {

Player[] players = new Player[3];

players[0] = new QuarterBack("Russel Wilson");

players[1] = new Receiver("Tyler Lockett");

players[2] = new Lineman("BJ Finney");

System.out.println("***** Offencive Plays *****");

displayPlays(players);

turnover(players);

System.out.println(" ***** Defencive Plays *****");

displayPlays(players);

}

public void displayPlays(Player[] players) {

for(Player player : players) {

System.out.println(player.name + " " + player.play());

}

}

public void turnover(Player[] players) {

for(Player player : players) {

player.turnover();

}

}

public static void main(String[] args) {

Football football = new Football();

football.play();

}

}

Sample output:

***** Offencive Plays ***** Russel Wilson throws a seem route Tyler Lockett runs a slant route BJ Finney Block Defenders

***** Defencive Plays ***** Russel Wilson not playing Tyler Lockett not playing BJ Finney Strip a ball from runners hands
