Code of Elevator System
Write object-oriented code to implement the design of the elevator system problem.
We’ve discussed different aspects of the elevator system and observed the attributes attached to the problem using various UML diagrams. Let’s explore the more practical side of things, where we will work on implementing the elevator 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 elevator control system:
Java
C#
Python
C++
JavaScript
Elevator system classes
In this section, we’ll provide the skeleton code of the classes designed in the class diagram lesson.
Note: For simplicity, we aren’t defining getter and setter functions. The reader can assume that all class attributes are private and accessed through their respective public getter methods and modified only through their public methods function.
Enumerations
First of all, we will define all the enumerationsElevatorState
, Direction
and DoorState
. The code to implement these enumerations is as follows:
Note: JavaScript does not support enumerations, so we will be using the
Object.freeze()
method as an alternative that freezes an object and prevents further modifications.
