+# Simple-Online-Store
+A Simple Online Store App that built with Java
+
+Developed a simple sales management application in Java that displays the product list, allows products to be added to the shopping cart, and calculates the grand total of the invoice. The Application runs via the command line and interacts with the user using the products ID. The project reflects my skills in programming and designing small applications
