🤖 Java Mentor Bot

An AI-powered educational chatbot designed to help beginners learn Java programming through clear, step-by-step explanations using a console-based interface.

This project demonstrates how artificial intelligence can be integrated into backend applications to create intelligent, interactive learning tools.

🎯 Project Objective

The goal of Java Mentor Bot is to act as a patient virtual Java tutor that:

• Explains core Java concepts clearly
• Guides beginners step-by-step
• Combines deterministic knowledge with AI-driven explanations

The system prioritizes reliability, clarity, and educational value.

🧠 How It Works (Architecture Overview)

The bot follows a Retrieval-Augmented Generation (RAG) approach:

1. User submits a Java-related question
2. The system first searches a local knowledge base
3. If the answer exists, it is returned instantly
4. Otherwise, the request is sent to an AI API for dynamic explanation
5. The response is formatted in a beginner-friendly teaching style

This approach ensures both accuracy and flexibility.
