JAVA 디자인 모델-공장 모델

1.공장 방법 모델

interface BeerFactory{
    void createBeer();
}
class QingDaoBeerFactory implements BeerFactory{
    @Override
    public void createBeer() {
        System.out.println("         ");
    }
}
class XueHuaBeerFactory implements BeerFactory{
    @Override
    public void createBeer() {
        System.out.println("         ");
    }
}
class FactoryMethod{
    public static void main(String[] args) {
        BeerFactory qingDao=new QingDaoBeerFactory();
        BeerFactory xueHua=new XueHuaBeerFactory();
    }    
}
