Java Based Jewelry shop management system where, The Jewelry Shop Management System is a Java-based application designed to help jewelry store owners efficiently manage customer information, sales records, and loyalty programs. Traditional methods of record-keeping, such as manual logs or spreadsheets, are often prone to errors and inefficiencies. This system provides a digital solution by storing customer details, purchase history, and loyalty points in an organized manner. The program uses file handling to ensure data is saved permanently, even after the application is closed. By automating key tasks like loyalty point calculations and sales tracking, the system reduces manual work and minimizes mistakes. The goal of this project is to create a simple yet effective tool that improves the daily operations of small to medium-sized jewelry businesses.
