Factory Design Pattern

Make a UFO

EnemyShipTesting.java public static void main(String[] args){ // Create the factory object EnemyShipFactory shipFactory = new EnemyShipFactory();

UFO Rocket Boss UFO EnemyShipFactory.java public EnemyShip makeEnemyShip(String newShipType) {

public String getName() { return name; } public void setName(String newName) { name = newName; }

} else if (newShipType.equals("R")){

System.out.print("What type of ship? (U / R / B)");

return new RocketEnemyShip();

if (userInput.hasNextLine()){

} else

String typeOfShip = userInput.nextLine();

if (newShipType.equals("B")){

theEnemy = shipFactory.makeEnemyShip(typeOfShip);

public class BigUFOEnemyShip extends EnemyShip { public BigUFOEnemyShip(){

private String name; private double speed; private double damage;

return new UFOEnemyShip();

Scanner userInput = new Scanner(System.in);

BigUFOEnemyShip

public abstract class EnemyShip {

if (newShipType.equals("U")){

EnemyShip theEnemy = null;

}

UFOEnemyShip public class UFOEnemyShip extends EnemyShip { public UFOEnemyShip(){

setName("Big UFO Enemy Ship"); setDamage(40.0); setSpeed(10.0);

}

}

setName("UFO Enemy Ship"); setDamage(20.0); setDamage(20.0);

}

}

public double getDamage() { return amtDamage; } public void setDamage(double newDamage) { amtDamage = newDamage; }

return new BigUFOEnemyShip();

if(theEnemy != null){

} else System.out.print("Please enter U, R, or B next time");

EnemyShip.java

EnemyShip newShip = null;

// Enemy ship object

doStuffEnemy(theEnemy);

name speed damage

} else return null; }

}

The Factory Pattern allows you to create objects without specifying the exact class of object that will be created.
