"Smart Budget Planner – My First Step into Web + Java Integration"

💡 Smart Budget Planner: Integrating Java Backend with Web Frontend to Build a Real-World Budgeting Tool

👋 Introduction

In a world where budgeting is key to managing personal finances, I wanted to create something simple yet impactful. That's how the Smart Budget Planner came into existence — a project built with a Java backend and a web-based frontend using HTML, CSS, and JavaScript.

This project was not just a technical exercise, but a hands-on journey to understand how backend logic can be combined with an interactive user interface to create a meaningful application.

🎯 Objective

The goal was to build a user-friendly tool that allows users to: ✅ Log in with their name ✅ Choose from different budget planning types (Personal, Travel, Festival) ✅ View a detailed breakdown of their expenses based on selected category ✅ Experience smooth interaction through a visually appealing UI

🛠️ Key Features Implemented

• 🧍♂️ Login System – User enters their name to begin
• 🏠 Home Page – Lets users pick the type of planner
• 📊 Output Page – Displays calculated budget with expense categories
• 🌄 Background Images – Themed pages for visual enhancement
• 📱 Responsive Layout – Basic responsiveness for different screens
• 💻 Backend-Frontend Sync – Logic written in Java matched with JS handling in UI

📐 Project Workflow

1. User lands on login page – Enters name
2. Redirects to home page – Picks type of plan
3. Redirects to output page – Java calculates budget and distributes across categories (e.g., food, travel, savings)
4. Frontend displays the result in a clean, easy-to-read format
