Chapter 22: Section 22.2, p. 414

The following code:

class Cat extends Animal {
  Cat() {
    super() {
  }

  void bark() {
    println("MEOW");
  }
}

should be:

class Cat extends Animal {
  Cat() {
    super() {
  }

  void meow() {
    println("MEOW");
  }
}

and the code comment should read:


Since meow() is not part of the parent class, we have to define it in the child class.
