I’m putting together a simple, learning-oriented e-commerce web application in Java and would like clean, well-commented code that I can study and extend later. The core flow is straightforward: a visitor lands on the site as a Guest, registers or logs in to become a Customer, browses a product catalogue, adds items to a cart, and submits an order—no payment gateway needed. Role management must cover Admin, Customer, and Guest. From the Admin dashboard I need the ability to Add, Edit, and Delete products, view every order that comes through, and manage the user list. For data storage we’ll use MySQL; please include a schema script plus any sample seed data so the app is ready to run after import. I’m comfortable running the project with Maven or Gradle, so ...

...refreshing only the in-game HUD of our Java + React title and want every health and status bar redrawn as a horizontal, arcade-era pixel strip that feels as if it were lifted straight from a 1980s cabinet. The rest of the code base and gameplay loop stay exactly as they are; your work lives purely in the React UI layer and the sprite sheet you supply. Here is what I need you to do: • Design a cohesive pixel-art skin for the health and status bars, sized for 1080p but readable down to 720p. • Deliver the pixel sprites (PNG and source Aseprite/PSD) plus the accompanying React component that swaps the current SVG/CSS bar with the new artwork while preserving all existing props and data bindings. • Hand off any small helper functions or CSS tweaks necessary so th...
