🗳️ Voting System in Java (OOP-Based)

A console-based Voting System built using Java and Object-Oriented Programming (OOP) principles. This project demonstrates real-world voting logic, including age validation, unique voter identification, duplicate vote prevention, and tie handling. Ideal for beginners, college mini-projects, and practicing Java OOP concepts.

🚀 Features

• ✅ Age Validation: Only voters aged 18 and above can participate.
• 🆔 Unique Voter ID: Each voter must provide a unique identifier.
• 🚫 Duplicate Vote Prevention: Ensures no voter can cast multiple votes.
• 🗳️ Multi-Candidate Voting: Support for voting among multiple candidates.
• 📊 Vote Counting and Results: Displays final vote tallies and outcomes.
• ⚖️ Automatic Tie Detection: Handles scenarios where candidates tie for the lead.
• 🧩 Modular OOP Design: Clean, encapsulated classes for maintainability.

🧠 Concepts Used

• Object-Oriented Programming (OOP)
• Classes and Objects
• Encapsulation
• Arrays and Collections (e.g., HashSet, ArrayList)
• Loops and Conditional Statements
• Scanner for User Input

🏗️ Project Structure

VotingSystem.java   # Main class to run the application
Election.java       # Handles voting logic and validations
Candidate.java      # Model class for candidates
Voter.java          # Model class for voters

▶️ How to Run

1. Clone the Repository:

   git clone <repository-url>
   cd voting-system-java

2. Compile the Code:

   javac *.java

3. Run the Application:

   java VotingSystem

🔒 Key Highlights

• 🆔 Voter ID Validation: Ensures every voter provides a unique ID; duplicates are rejected automatically.
• 🚫 Duplicate Vote Prevention: Tracks voted IDs using a HashSet to allow only one vote per voter.
• ⚖️ Tie Handling: If candidates tie for the highest votes, the result is declared as a tie.

🌱 Future Enhancements

• Integrate file or database storage for voter and election data.
• Add an admin panel for candidate management.
• Develop a GUI version using Swing or JavaFX.
• Transform into a REST API with Spring Boot.
