Write a Java program to create an Animal interface with a method called bark() that takes no arguments and returns void. Create a Dog class that implements Animal and overrides speak() to print “Dog is barking”.

interface Animal {
void bark();
}

class Dog implements Animal {
public void bark() {
System.out.println(“Dog is barking”);
}
}

public class TestAnimal {
public static void main(String[] args) {
Animal d = new Dog();
d.bark();
}
}

Output:
