Animal goose = AnimalFactory.create("Goose");
Animal dog = AnimalFactory.create("Dog");
Animal cow = AnimalFactory.create("Cow");

goose.makeSound(); // Honk
dog.makeSound(); // Woof

Answer 1

interface Animal {
    public void makeSound();
}

class Goose implements Animal {

    @Override
    public void makeSound() {
        System.out.println("Honk");
    }
}

class Dog implements Animal {

    @Override
    public void makeSound() {
        System.out.println("Woof");
    }
}

class Cow implements Animal {

    @Override
    public void makeSound() {
        System.out.println("mooo");
    }
}

class AnimalFactory {


    public static Animal create(String type) {
        if (type.equalsIgnoreCase(Goose.class.getSimpleName())) {
            return new Goose();
        } else if (type.equalsIgnoreCase(Dog.class.getSimpleName())) {
            return new Dog();
        } else {
            return new Cow();
        }
    }
}

class AnimalTest {

    public static void main(String[] args) {
        Animal goose = AnimalFactory.create("Goose");
        Animal dog = AnimalFactory.create("Dog");
        Animal cow = AnimalFactory.create("Cow");

        goose.makeSound(); // Honk
        dog.makeSound(); // Woof
        cow.makeSound(); // mooo
    }
}
