◈ Overview

CodingVibes is a desktop storefront for programming courses, written in plain Java Swing. A visitor picks the Admin or User entry on the landing page, signs up or logs in, browses language courses, fills a cart and walks through a payment screen. Admins get a separate dashboard to add and remove users and add developers.

It is an academic project made for a university course to practise object-oriented design and event-driven GUI programming. Everything commercial is a simulation: there is no real payment, no database and no network access. Accounts live in plain-text files, so it is not a model of secure authentication.

◈ Highlights

Two entry roles Landing page splits into Admin and User login, plus a user sign-up form.	Course catalogue Two catalogue pages and a detail window per language (Java, Python, C++, Kotlin, Go and more).	Shopping cart Add and remove courses; the cart is held in memory for the session.
Simulated payments Card, bKash, Nagad, Rocket and generic mobile payment screens ending in a confirmation page.	Admin dashboard Add users, remove users, view registered users and add developers.	Content pages About us, vision and mission, team, blog, reviews, contact and special services.
Flat-file storage User and admin records are appended to and read from Data/*.txt with java.io.	Plain Swing, no dependencies Only the JDK is needed: Swing, AWT and the standard library.	About 7.8k lines One class per screen across 54 Java files, split into main and interfaces.

User login	Main menu
Course catalogue	Course details
Shopping cart	Payment options (simulated)
Admin dashboard	User management

◈ Architecture

Each screen is a JFrame in the SourceFiles package. Screens open each other directly. The only shared state is a static cart list and the text files under Data/.

◈ Tech Stack

Layer	Technologies	Purpose
Language	Java (JDK 17 or later recommended)	Application logic and OOP structure
GUI	Swing and AWT	Windows, tables, buttons, event listeners
Storage	java.io text files	User and admin records under Data/
Assets	PNG and JPG in assets/	Backgrounds, logos and language icons
Tooling	Any Java IDE	IntelliJ IDEA, Eclipse or NetBeans

◈ Getting Started

Prerequisites: a JDK (17 or later is recommended) and an IDE or the javac command line.

git clone https://github.com/Saji-d/codingvibes-java-gui.git
cd codingvibes-java-gui

The screens read images and data files with relative paths, so run from a working directory that contains assets/ and a Data/ folder with User_Data.txt and Admin_Data.txt. The Data/ folder is not tracked in this repository, so create it and add an admin record before using the admin login. Then open the project in your IDE and run the entry point:

src/main/Start.java   (opens the Page landing screen)

The public class in Start.java is declared as start in lower case. If your compiler rejects the file name mismatch, rename the class to Start.

Payments, the cart, reviews, contact details and user data are simulations for learning only.
