換皮膚？系列工廠/抽象工廠(模式)的實現

有時候我們見到換皮膚,切換系列產品(族),是不是所有代碼重新來過一遍呢,不是的,這時候抽象工廠/系列工廠模式應運而用.抽象工廠的基本脈絡就是繼承於父級產品類的多個抽象產品類的具體實現。

以下是實現:

/**
 * 工廠的父類-抽象工廠-產生系列產品的方法
 * @author Rick

 */
public abstract class AbstractFactory {
public abstract Vechicle createVehicle();
public abstract Weapon createWeapon();
public abstract Food createFood();
}

-------------------------------------------------------------------------------------------------------------------------

public class AK47 extends Weapon {
public void shoot() {
System.out.println("пепепе...");
}
}

-------------------------------------------------------------------------------------------------------------------------

public class Apple extends Food {
public void printName() {
System.out.println("apple"); 
}
}

-------------------------------------------------------------------------------------------------------------------------

public class Broom extends Vechicle {


public void run() {
System.out.println("һ·ɳӾѩ؉Ѽ׸4broom...");
}

}

----------------------------------------------------------------------------------------------------------------------

/**

public class Car extends Vechicle {

public void run() {
System.out.println("ð؅ҌѼƜאcar...");
}
}

-------------------------------------------------------------------------------------------------------------------------

public class DefaultFactory extends AbstractFactory {


@Override
public Vechicle createVehicle() {
// TODO Auto-generated method stub
return new Car();
}


@Override
public Weapon createWeapon() {
// TODO Auto-generated method stub
return new AK47();
}


@Override
public Food createFood() {
// TODO Auto-generated method stub
return new Apple();
}

}

--------------------------------------------------------------------------------------

public abstract class Food {
public abstract void printName();
}

--------------------------------------------------------------------------------------

public class MagicFactory extends AbstractFactory {
public Broom createBroom() {
return new Broom();
}

public MagicStick createMagicStick() {
return new MagicStick();
}

public MushRoom createMushRoom() {
return new MushRoom();
}


@Override
public Vechicle createVehicle() {

return new Broom();
}


@Override
public Weapon createWeapon() {

return new MagicStick();
}


@Override
public Food createFood() {

return new MushRoom();
}
}

----------------------------------------------------------------------------------------------------------------------------------

public class MagicStick extends Weapon {


@Override
public void shoot() {
System.out.println("Fire hu hu hu ...");
}

}

----------------------------------------------------------------------------------------------------------------------------------

public interface Moveable {
void run();
}

-----------------------------------------------------------------------------------------------------------------------------------

public class MushRoom extends Food {


@Override
public void printName() {
System.out.println("mushroom...");
}


}

-----------------------------------------------------------------------------------------------------------------------------------

/**
 * 系列產品
 * @author Rick

 */
public class Test {
public static void main(String[] args) {
// DefaultFactory f = new DefaultFactory();
AbstractFactory f = new MagicFactory();
Vechicle v = f.createVehicle();
v.run();
Weapon w = f.createWeapon();
w.shoot();
Food a = f.createFood();
a.printName();
}
}

----------------------------------------------------------------------------------------------------------------------

public abstract class Vechicle {
public abstract void run();
}

----------------------------------------------------------------------------------------------------------------------

public abstract class Weapon {
public abstract void shoot();
}

起航！TAMAO!
