Offline Expense Splitter

A small, local JavaFX app to split expenses between people and generate friendly settlement instructions (e.g., "Ayush will pay Dhruv ₹250.00").

This repository contains a compact JavaFX implementation (Main.java) that:

• Accepts a list of people and their expenses (expense can be left blank and will be treated as ₹0.00). This fixes missing participants like "Sakhi" when they haven't paid anything yet.
• Computes the per-person share and generates grouped, human-friendly settlement sentences (payers grouped with multiple payees joined by "and").
• Uses a simple, clean light background and larger, attractive fonts for readability.

Features

• Include participants with blank expense (treat as 0).
• Grouped settlement lines for concise reading ("Lekha will pay Sammra ₹120.00 and Sakhi ₹30.00").
• Friendly emoji-enhanced UI and premium styling.

How to run (macOS / Linux / Windows)

Prerequisites

• Java 11+ (OpenJDK or Oracle JDK).
• JavaFX SDK matching your JDK version. Download from https://openjfx.io/ if you don't have it.

Compile and run (replace /path/to/javafx/lib with your JavaFX SDK lib directory):

# from the project folder
# compile
javac Main.java

# run (example for macOS/Linux; on Windows adjust the path separators)
java --module-path /path/to/javafx/lib --add-modules javafx.controls,javafx.fxml Main

Note: If you use an IDE like IntelliJ IDEA or Eclipse, add the JavaFX SDK as a library/module and run Main as a Java application.

Quick usage

1. Click "+ Add Person" to add rows.
2. Enter names and expenses (expense field may be left blank for people who haven't paid anything).
3. Click "⚡ Split Expenses".

Example scenario (to reproduce the sample outputs):

• Ayush: leave blank (or 0)
• Dhruv: 250
• Lekha: 120
• Sammra: 0
• Sakhi: 30

Expected summarized output (example):

➡️ Ayush will pay Dhruv ₹250.00 ➡️ Lekha will pay Sammra ₹120.00 and Sakhi ₹30.00

Notes

• The app treats malformed expense numbers by skipping that row (you can improve validation to show inline errors).
• JavaFX is required at runtime. If you'd like, I can add a Gradle wrapper or a small build script that bundles JavaFX using jlink or javafx-maven-plugin for an easier run experience.

Next steps I can implement for you

• Add a styled TextFlow summary with bold payers and highlighted amounts.
• Add a "Copy summary" button to copy the settlement text to clipboard and an "Export" button for CSV.
• Add input validation with inline error hints.

Add your logo

To show your logo inside the app place a PNG named logo.png in the project root (same folder as Main.java) or in resources/logo.png. When the app finds that file it will show the logo next to the application title. If you package the app, you can also bundle logo.png on the classpath at /logo.png.

Suggested logo size

• For best results use a square PNG around 256×256 — the app will scale it down to fit beside the title.

If you'd like any of those, or want me to try compiling/running here, tell me which one—if you want me to run the app here, provide the path to your JavaFX SDK (or confirm it's installed) so I can run it and verify the UI changes live.
