设计模式之抽象工厂模式

设计模式之--抽象工厂模式

1,定义:提供一个创建一系列相关或者相互依赖对象的接口,而无需制定它们具体的类;

2,下面是抽象工厂模式的结构图:

 

3,抽象工厂模式的实现代码:

    1),结构图:

 

 

    2),代码

入口类Main.class:

public class Main {

  public static void main(String[] args) {                                                                                                                                              

    BreadMaker breadMaker;

    PizzaMaker pizzaMaker;

    System.out.println("小面的面包店开业了");

    System.out.println("顾客要买黑色面包");

    IFactory breadFactory = new BlackBreadFactory();

    breadMaker = breadFactory.CreateBread();

    breadMaker.GetBread();

    System.out.println("顾客要黑色巧克力披萨");

    pizzaMaker = breadFactory.CreatePizza();

    pizzaMaker.GetPizza();

  }

}

 

工厂接口类IFactory.class:

public interface IFactory {

  BreadMaker CreateBread();

  PizzaMaker CreatePizza();

}

 

三个工厂类:

BlackBreadFactory.class,HoneyBreadFactory.class,WhiteBreadFactory.class:

public class BlackBreadFactory implements IFactory{

  @Override

  public BreadMaker CreateBread() {

    // TODO Auto-generated method stub

    return new BlackBread();

  }

  @Override

  public PizzaMaker CreatePizza() {

    // TODO Auto-generated method stub

    return new BlackPizza();

  }

}

 

public class HoneyBreadFactory implements IFactory{

  @Override

  public BreadMaker CreateBread() {

    // TODO Auto-generated method stub

    return new HoneyBread();

  }

  @Override

  public PizzaMaker CreatePizza() {

    // TODO Auto-generated method stub

    return new HoneyPizza();

  }

}

 

public class WhiteBreadFactory implements IFactory{

  @Override

  public BreadMaker CreateBread() {

    // TODO Auto-generated method stub

    return new WhiteBlead();

  }

  @Override

  public PizzaMaker CreatePizza() {

    // TODO Auto-generated method stub

    return new WhitePizza();

  }

}

 

两个父类:

BreadMaker,PizzaMaker:

public class BreadMaker {

  public void GetBread(){ }

}

 

public class PizzaMaker {

  public void GetPizza(){ }

}

 

相关子类:

BlackBread,BlackPizza,HoneyBread,HoneyPizza,WhiteBlead,WhitePizza:

public class BlackBread extends BreadMaker{

  @Override

  public void GetBread() {

    // TODO Auto-generated method stub

    super.GetBread();

    System.out.println("小面做出了黑巧克力面包");

  }

}

 

public class BlackPizza extends PizzaMaker{

  @Override

  public void GetPizza() {

    // TODO Auto-generated method stub

    super.GetPizza();

    System.out.println("小面做出了黑巧克力披萨");

  }

}

 

public class HoneyBread extends BreadMaker{

  @Override

  public void GetBread() {

    // TODO Auto-generated method stub

    super.GetBread();

    System.out.println("小面做出了蜂蜜面包");

  }

}

 

public class HoneyPizza extends PizzaMaker{

  @Override

  public void GetPizza() {

    // TODO Auto-generated method stub

    super.GetPizza();

    System.out.println("小面烤出了蜂蜜披萨");

  }

}

 

public class WhiteBlead extends BreadMaker{

  @Override

  public void GetBread() {

    // TODO Auto-generated method stub

    super.GetBread();

    System.out.println("小面做出了白色巧克力面包");

  }

}

 

public class WhitePizza extends PizzaMaker{

  @Override

  public void GetPizza() {

    // TODO Auto-generated method stub

    super.GetPizza();

    System.out.println("小面做出了白巧克力披萨");

  }

}

 

    3),运行结果:

    

3,抽象工厂模式适用情况:

    1),一个系列要独立于它的产品创建、组合和表示时;

    2),一个系列要由于多个产品系列中的一个来配置时;

    3),当要强调一系列相关的产品对象的设计以便进行联合使用时;

    4),当要提供一个产品类库,而只有显示它们的接口而不是实现时;
