Course: BCS306A – Object Oriented Programming with Java

Student Name: [Your Name] | USN: [Your USN]

Introduction

The Smart City Management System is a Java-based Mini Project designed to simulate the automation of urban infrastructure. Leveraging Object-Oriented Programming (OOP) principles, this application creates a centralized controller for city resources. It addresses the growing need for efficient resource management in modern urbanization, integrating modules like automated lighting, traffic sensing, and waste monitoring into a cohesive system architecture.

Problem Statement: Rapid urban expansion leads to unmanaged resource consumption. Traditional systems lack real-time monitoring and automated data processing, resulting in energy waste and traffic congestion.

Focus: Automation & Efficiency

Project Objectives

To design a modular system using Java Classes and Interfaces.

To implement Inheritance to manage different device types (Sensors, Actuators).

To demonstrate Polymorphism in handling diverse city inputs simultaneously.

To develop a Console or GUI-based output to visualize system status.

Expected Optimization Impact

By implementing this OOP-based Smart System, we anticipate significant reductions in resource wastage compared to legacy systems. This demonstrates the efficiency of algorithmic control.

Source Code: Abstract Device

// Base class for all smart devices abstract class SmartDevice { protected String deviceId; protected boolean isActive; public SmartDevice(String id) { this.deviceId = id; this.isActive = false; } abstract void operate(); public void togglePower() { isActive = !isActive; System.out.println(deviceId + " Power: " + isActive); } }

Source Code: Implementation

// Concrete class for Smart Lighting class SmartLight extends SmartDevice { private int brightnessLevel; public SmartLight(String id) { super(id); this.brightnessLevel = 0; } @Override void operate() { if (isActive) { brightnessLevel = 100; System.out.println(deviceId + " operating at " + brightnessLevel + "%"); } } }

System Output Screens

The console output confirms the Polymorphic behavior. When the 'operate()' method is called on the list of devices, the SmartLight and TrafficSensor objects respond according to their specific logic defined in the extended classes. This validates the OOP structure required for the BCS306A evaluation.

Conclusion

Successfully utilized Java Abstract Classes to create a scalable architecture.

Smart City simulation demonstrates how OOP solves complex real-world modeling.

Future scope includes adding a Database (MySQL) and a GUI (JavaFX).
