To-Do List (Java REST + HTML/JS) ✅

This is a full-stack to-do list web application where the backend is built with Java and the frontend uses HTML and JavaScript.
Think of it like a digital sticky note board where the server acts as the brain storing all your notes, and the browser is the hand moving them around.

🧠 Features

• 📝 Add, update, delete, and view to-do tasks
• 📡 RESTful API built with Java
• 🌐 Frontend built with HTML + JavaScript
• 🔄 Real-time interaction using asynchronous requests
• 🐳 Docker-compatible
• ☕ Runs as a Java JAR file via Maven

⚙️ Tech Stack

Layer	Technology
Backend	Java, Maven, REST API
Frontend	HTML, CSS, JavaScript
Packaging	JAR executable
Deployment	Docker, render.yaml

🚀 How It Works

1. Frontend (HTML/JS) sends requests like:
   “Hey server, add this new task: 'Buy oat milk' 🛒”

2. Backend (Java REST API) receives the request, stores it, and replies with a confirmation.

3. The frontend updates instantly — no need to refresh the page.

It’s like passing messages between two smart roommates: one who handles the UI (browser) and one who manages storage (server).
