工厂方法模式

抽象工厂定义一个用于创建对象的接口，让子类决定类的实例化

public class PeachFactory implements Factory {
    @Override
    public Fruit get(){
        return new Peach();
    }
}
Peach

public class Peach implements Fruit {
    @Override
    public void eat(){

    }
}
Fruit

public interface Fruit{
    void eat();
}
Factory
content_copyfile_download

AppleFacrory
