Write the object-oriented code to implement the design of the restaurant management system problem.
Using various UML diagrams, we’ve covered different aspects of the restaurant management system and observed the attributes attached to the problem. Let us now explore the more practical side of things, where we will work on implementing the restaurant management system 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 RMS:
Java
C#
Python
C++
JavaScript
If you want to skip directly to the implementation and see the complete workflow, simply scroll down or click Executable Code: Restaurant Management System.
Restaurant management system 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 can assume that all class attributes are private, accessed through their respective public getter methods, and modified only through their public method functions.
Enumerations and custom data type
The following code defines the enumeration and custom data type used in the restaurant management system.
