class Animal {
    protected String name;
    public Animal() {
        name = "Animal";
    }
    public String getName() {
        return name;
    }
}
class Dog extends Animal {
    private String breed;
    public Dog(String breed) {
        this.breed = breed;
    }
    public String getBreed() {
        return breed;
    }
}
public class Main {
    public static void main(String[] args) {
        Dog dog = new Dog("Labrador Retriever");
        System.out.println("Name: " + dog.getName());
        System.out.println("Breed: " + dog.getBreed());
