Algorithms and Data Structures in an Object-Oriented Framework (“ADSOOF”)

Code for “Inheritance” section

• DrinksMachine.java The file describes what is inside a DrinksMachine object, and how the methods that may be called on it work.
• Can.java The file describes what is inside a Can object, and how the methods that may be called on it work.
• EmptyCanException.java This file is needed when you have file Can.java as code in this class uses it, but no direct reference is made to it in this section.
• DrinksMachineOps.java This file contains some static methods which take DrinksMachine objects as arguments.
• ExtDrinksMachine1.java A file which extends the class defined in DrinksMachine.java by adding extra methods.
• ExtDrinksMachine2.java A file which extends the class defined in DrinksMachine.java by adding extra methods and changing the behaviour of some existing methods.
• DrinksCompany.java A file defining DrinksCompany objects, which are used by ExtDrinksMachine2 objects.
• UseDrinksMachines5.java A program demonstrating the creation and use of an ExtDrinksMachine1 object alongside a DrinksMachine object.
• UseDrinksMachines6.java A program demonstrating the creation and use of an ExtDrinksMachine2 object alongside a DrinksMachine object.
• ExtDrinksMachine1a.java A file which implements what was done in ExtDrinksMachine1.java, but uses composition rather than inheritance.
• UseDrinksMachines7.java Front end code showing the use of an ExtDrinksMachine1a object alongside a DrinksMachine object.
