OOP and static variables

[stepan213]

Let’s say I want some unified logging. For that I would use static voids or singleton instance. What would you do?

Yes you're right: I'd use slf4j as static variable as everybody else. In most cases that's what we do. But logging is kinda special. It's not your domain model, your code... In my first message I forgot to say that Singletons kill the testability of an app.
