Java 11 to 21: A Visual Guide for Seamless Migration

Dec 07, 2023 · Otavio Santana

Thank you for the article.

In addition to the useful pieces of advice, I liked a lot the parallels you made throughout the article when providing arguments for the migration from Java 11 to Java 21.

I have a small observation though - in the first part, there are a few places where you say the migration is from 21 to 11. I think you meant the opposite and it would be nice to correct it for the future readers.
