        feed.Feed(an);
    }
}

        System.out.println("Dog eating");
    }
    public void eats(){
        System.out.println("Dogs eating");
    }
}
class Cat{
    public void eat(){
        System.out.println("Cat eating");
    }
    public void eats(){
        System.out.println("Cats eating");
    }
}
class Feeder{
    public void Feed(String animal){
        int i = 0;
        if(animal.equals("Dog")){
            i=1;
        }else if(animal.equals("Dogs")){

        }
    }
}
