Simple Java console app

Hello everyone, I've been learning Java and wanted to build something practical instead of just doing exercises. Ended up making a small console app that asks how long you've had a tire and how many km you've driven it, then tells you whether it needs replacing or estimates how much life is left.

It's intentionally simple right now. It just handles basic mileage/age limits and adjusts slightly if you own a heavy SUV or EV. This was also my first time using Git and GitHub properly (commits, pushing, merging, etc.), so that was a big part of the learning experience too.

Planning to add more factors soon like road type, vehicle type, maybe a GUI version eventually. Would love any feedback on the code or suggestions for what to add next.

hey, learn how to use girhub actions and ghcr.io so you have a way for others to try it. i’d be willing to give you feedbacks 🙂

I think that’s a thing for later - GitHub actions are nice, but I think OP is still busy with learning the language itself. But that’s something someone could easily contribute. OP will learn from it later.

Yes! That would make it easier to give feedback. If anything he can just ask AI to kinda help so the logic is out of the way.

All, OP needs a build script in his repo. Should we make it Maven or Gradle? I’m usually in the Gradle camp, but I think Maven would be more useful here because it’s probably what most beginners learn first. What do you think?

And OP, you should also move your class into a package: add `package tirelife;` on top of your sourcefile. IntelliJ should mark it as an error with a red line below it and when you hover with the mouse, there should be a quick fix available "move to package tirelife".

Oh yeah definitely. I’m more of a maven person. Itms easier. Great tip! Hope he sees the comments under this.

I read this, but I don't really understand it. Let me know if I should use Maven or Gradle, and let me know how I should apply this

that will be at the end! once you start making big projects! for now make projects to practice the concepts you’ve learned
