设计模式之工厂模式（Java）

//接口与产品实体类
//共同使用的接口
interface  phone{
  public void run();
  public void stop();
}
//具体实现类miphone
class miPhone implements phone{
  @Override
  public void run() { 
    System.out.println("miphone run!");
  }
  @Override
  public void stop() { 
    System.out.println("miphone stop!");
  }
}
//具体实现类iPhone 
class iPhone implements phone{
  @Override
  public void run() { 
    System.out.println("iPhone run!");
  }
  @Override
  public void stop() { 
    System.out.println("iPhone stop!");
  }
}

//具体工厂类
class phoneFactory{
  public static phone getPhoneInstance(String phone) {
    if(phone.equals("iPhone")){
      return new iPhone();
    }else if(phone.equals("miPhone")) {
      return new miPhone();
    }else {
      System.out.println("本工厂不能生产该种手机！");
      return null;
    }
  }
}

public class factorydemo { 
  public static void main(String[] args) {
//    创建一个生产手机得工厂
    phoneFactory phonex = new phoneFactory();
//    与小米公司合作生产小米手机
    phone miPhonex = phoneFactory.getPhoneInstance("miPhone");
    miPhonex.run();
    miPhonex.stop();
//    与苹果公司合作生产苹果 手机
    phone iPhonex = phoneFactory.getPhoneInstance("iPhone");
    iPhonex.run();
    iPhonex.stop();
  }
}

//工厂类
class phoneFactory{
  public static phone getMiPhone() {
    return new miPhone();
  }
  public static phone getIPhone() {
    return new iPhone();
  }
}
//实验类
public class factorydemo {
  public static void main(String[] args) {
    phone iPhonex = phoneFactory.getIPhone();
    iPhonex.run();
    iPhonex.stop();
    phone miphonex = phoneFactory.getMiPhone();
    miphonex.run();
    miphonex.stop();
  }
}

//抽象工厂类
 abstract class abstractFactory{
  public abstract iPhone createiPhone();
  public abstract miPhone createmiPhone();
}
//具体工厂类
 class phoneFactory extends abstractFactory{
  @Override
  public iPhone createiPhone() {
    return new iPhone();
  }
  @Override
  public miPhone createmiPhone() {
    return new miPhone();
  }
}
public class factorydemo {
  public static void main(String[] args) {
    phone iPhonex = new phoneFactory().createiPhone();
    iPhonex.run();
    iPhonex.stop();
    phone miphonex = new phoneFactory().createmiPhone();
    miphonex.run();
    miphonex.stop();
  }
}
