🎓 Grade Management System

A Java Swing-based desktop application designed to manage student academic records with login authentication. This project was developed using Object-Oriented Programming (OOP) concepts and a graphical interface designed via IntelliJ Swing UI Designer.

Users can log in through credentials stored in a simple Login.txt file, register new students, view and update their grades, and export transcripts with all through a friendly GUI.

💡 Project Overview

This application was originally created as part of an academic group project for the Object-Oriented Programming (KP14203) course at Universiti Malaysia Sabah (UMS).

It has since been cleaned, restructured, and published here as a portfolio project by the contributor with proper credit to the original group members.
