Subclasses

(Dog extends Animal

i.e. “A dog is an animal” or

“All dogs are animals”)

class Dog extends Animal {

public Dog() {

strNoise = “Woof”;

} // of constructor

public void doYourThing ( ) {

identifySelf();

System.out.println(“I am a dog”);

System.out.println(strNoise);

} // of doYourThing

} // of Dog

Recall: The Animal class had a no-op method for doYourThing()
