Hints

super(name) calls the parent constructor.

describe() in Animal calls whichever sound() the object really has.

Solution explanation

Overriding lets subclasses change one piece of behaviour while reusing the rest.

import java.util.Scanner;

class Animal {
    protected final String name;

    Animal(String name) {
        this.name = name;
    }

    String sound() {
        return "...";
    }

    String describe() {
        return name + " says " + sound();
    }
}

class Dog extends Animal {
    Dog(String name) {
        super(name);
    }

    @Override
    String sound() {
        return "woof";
    }
}

class Cat extends Animal {
    Cat(String name) {
        super(name);
    }

    @Override
    String sound() {
        return "meow";
    }
}

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int n = sc.nextInt();
        for (int i = 0; i < n; i++) {
            String type = sc.next();
            String name = sc.next();
            Animal a = type.equals("dog") ? new Dog(name) : type.equals("cat") ? new Cat(name) : new Animal(name);
            System.out.println(a.describe());
        }
    }
}
