Hi @rlaehd62,

Congratulations on submitting your first PR for the Spring Framework! 👍

Unfortunately, the proposed changes pertain mainly to topics that are a matter of style, and we typically do not like to make changes based solely on style. In addition, if-else blocks sometimes actually make it easier to reason about the code at a glance.

In light of that, I am closing this PR.

Cheers,

Sam
