A good answer might be:

Yes---any number of classes can implement the same interface.

The Completed Book Class

There is one remaining class in our example, Book, which looks like this:

  • Has a parent Goods.
  • Adds a variable author.
  • Is taxable.
You might wish to review the diagram that shows the relationships between the classes. Here is the usual blank-ridden class definition: 

class Book  ____________ Goods ____________ Taxable
{
  String ____________;

  Book( String des, double pr, String auth)
  {
    super( des, pr );
    ___________  = auth ;
  }

  void display()
  {
    super.display() ;
    System.out.println( "author: " + ______________ );
  }

  public double ____________()
  {
    return price * ____________ ;
  }
}

You might wish to consult the Taxable interface.
