Java设计模式之抽象工厂(02)

对工厂方法进行抽象。当增加新的产品时，不用改动工厂类。而是集成已有的工厂接口或者抽象工厂，创建新的工厂。这就是对扩展开发，对修改封闭。

package Pak;

public abstract class Automobile {
    public abstract void Run();
}

package Pak;

public class Bus extends Automobile {

    @Override
    public void Run() {
        System.out.println("Bus Run");
    }
}

package Pak;

public class Jeep extends Automobile {

    @Override
    public void Run() {
        System.out.println("Jeep Run.");
    }
}

package Pak;

public interface IProduce {
    public Automobile Produce();
}

package Pak;

public class BusFactory implements IProduce {
    @Override
    public Automobile Produce() {
        // TODO Auto-generated method stub
        return new Bus();
    }
}

package Pak;

public class JeepFactory implements IProduce {
    @Override
    public Automobile Produce() {
        return new Jeep();
    }
}

package Pak;

public class Main {

    public static void main(String[] args) throws Exception {
        IProduce busFactory=new BusFactory();
        busFactory.Produce().Run();
        
        IProduce jeepFactory=new JeepFactory();
        jeepFactory.Produce().Run();
    }
}
