Ever wondered how a simple chat app works behind the scenes? In this video I walk you through QuickChat, a Java messaging app I built in NetBeans. Watch it in action: register, log in, then send, disregard or store messages. You'll see how the app checks phone numbers, limits messages to 250 characters, and creates a unique message ID and hash for every message. I also explain my code step by step, run my unit tests, and show GitHub Actions automatically testing my project every time I push. If you're a student learning Java, this might help you with your own project! GitHub: https://github.com/ndlovugift/ProjectPOE-P...
