Code for the Vending Machine
Explore how to translate a vending machine object-oriented design into executable code across multiple programming languages. Understand the roles of classes like Product, Rack, and Inventory, and see how the VendingMachine class manages state and transactions. Learn to run, modify, and extend this design to reinforce practical OOD interview skills.
We’ve reviewed different aspects of the vending machine problem and observed the attributes attached to the problem using various UML diagrams. Let us now explore the more practical side of things, where we will work on implementing the vending machine using multiple languages. This is usually the last step in an object-oriented design interview process.
We have chosen the following languages to write the skeleton code of the different classes present in the vending machine:
Java
C#
Python
C++
JavaScript

Vending machine classes
This section will provide the skeleton code of the classes designed in the class diagram lesson.
Note: For simplicity, we are not defining getter and setter functions. The reader ...
