What is output of the following code ?class Animal {void makeSound(){System.out.prntln("Animal sound");}}class Dog extends Animal {void makeSound(){System.out.println("Bark");}}public class Test{public static void main(String[] args) {Animal a = new Dog();a.makeSound();}}Question 19Answera.Runtime errorb.Barkc.Compilation errord.Animal soundClear my choice

What is the expected output?class Animal { Animal() { System.out.println("Animal"); }}class Wild extends Animal{ Wild() { System.out.println("Wild"); super(); }}public class Test { public static void main(String args[]) { Wild wild = new Wild(); }}
