[LT-1633] Enabled Checkstyle and reformatted code

[andras-markos]

Some minor refactorings are also included.

Please first review the previous PR!

@andras-markos I would not recommend those reformatting changes, as annoying as working with a non-standard format can be. Those changes will 100% ensure you will never be able to pull changes from the original project without a huge headache of having to resolve a bazillion conflicts.

My recommendation is to follow the original project's code formatting standards, as annoying as that may be.

Yeah, that makes sense.
I'll just decline this PR as the other one already has the bug fix and the Gradle build config update.
We can just keep Checkstyle off for this fork then. 😞
