[Java] 设计模式之工厂系列 02-面向抽象编程 抽象工厂 - 缺点 ： 产生新的产品品种的时候，改动太多

(1), JDK 中 factory 也是比比皆是。 (2), 抽象工厂 -- 换皮肤的软件

Vehicle

package com.bjsxt.dp.factory.abstractfactory;

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

Weapon

package com.bjsxt.dp.factory.abstractfactory;

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

Food

package com.bjsxt.dp.factory.abstractfactory;

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

AbstractFactory

package com.bjsxt.dp.factory.abstractfactory;

public abstract class AbstractFactory {
public abstract Vehicle createVehicle();
public abstract Weapon createWeapon();
public abstract Food createFood();

}

Carextends Vehicle

package com.bjsxt.dp.factory.abstractfactory;

public class Car extends Vehicle {

public void run() {
System.out.println("冒着烟奔跑中car.......");
}
}

Broom extends Vehicle

package com.bjsxt.dp.factory.abstractfactory;

public class Broom  extends Vehicle {

public void run() {
System.out.println("一路沙尘暴飞奔而来broom.....");
}

}

AK47
extends Weapon

package com.bjsxt.dp.factory.abstractfactory;

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

MagicStick extends Weapon

package com.bjsxt.dp.factory.abstractfactory;

public class MagicStick extends Weapon {

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

}

Apple extends Food

package com.bjsxt.dp.factory.abstractfactory;

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

MushRoom extends Food

package com.bjsxt.dp.factory.abstractfactory;

public class MushRoom extends Food {

@Override
public void printName() {
// TODO Auto-generated method stub
System.out.println("mushroom");
}

}

DefaultFactory extends AbstractFactory

package com.bjsxt.dp.factory.abstractfactory;

public class DefaultFactory extends AbstractFactory {

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

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

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

}

MagicFactory
extends AbstractFactory

package com.bjsxt.dp.factory.abstractfactory;

public class MagicFactory extends AbstractFactory {

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

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

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

}

抽象工厂针对是产品系列, 工厂方法则只是在子类中实例化对象，能控制生产过程。
