Hello good people, hoping you are all well and healthy. I am from doing a database project with Postgresql and I would be very grateful if I get any feedback on it. If there is any place I've gone against sql or architectural principles, also where I need to improve on..Will very much appreciate. github repository link: https://github.com/naftalmambo/sacco-management-backend

Java & Spring Boot developers, let’s have some fun. 😂👨🏽‍💻 Is this code fine, or does it have errors? If you see errors: - How many are there? - Are they compile-time or runtime errors? - What exactly is causing them? - How would you fix each one? Try to solve it without asking AI first 😂😂 Drop your answers below — let’s see who catches them all. 👀☕

1. Kafka Learning - Studied Kafka through a crash course and learned its internal working, use cases, and when Kafka should or should not be implemented. 2. Docker CoW Mechanism - Learned about Copy-on-Write (CoW), snapshots, coalescing, and how Docker uses these concepts internally. 3. Docker Layering & Storage - Studied Docker image/container layering, storage consumption, and limitations of layered snapshots. 4. Docker Persistent Storage - Learned how Docker volumes and bind mounts provide persistent storage and protect data from container crashes/removal. 5. Technical Discussion – Discussed CoW, snapshots, Docker layering, and storage behavior with Mr. Sujai Sir to improve conceptual understanding.

Every Spring Boot app you’ve ever run quietly creates, wires, and destroys objects for you, in other terms, this is Inversion of Control (IoC), a concept we’ll break down later. 1. Instantiation Spring creates the bean instance. 2. Dependency Injection Dependencies are injected (@Autowired, constructor injection, etc.). 3. Initialization (@PostConstruct) Custom setup logic runs after dependencies are ready. 4. Ready State Bean is fully initialized and used across the application. 5. Context Shutdown Application begins shutdown. 6. Cleanup (@PreDestroy) Cleanup logic runs (closing resources, connections). 7. Bean Destroyed Bean is removed and becomes eligible for garbage collection. Bean Scopes (Important) - Singleton (default): One instance per application - Prototype: New instance each time requested - Request / Session: Scoped to HTTP request or session
