I haven’t written Java in my day-to-day for quite some time now, but the first thing that came to mind for a good open source Java codebase is Guava by Google: https://github.com/google/guava

It’s a collection of core libraries for Java that I believe should have a lot of useful patterns/concepts to learn from.

I also highly recommend Effective Java by Joshua Bloch (https://www.amazon.com/Effective-Java-Joshua-Bloch/dp/013468...). An incredible text for any kind of programmer, and even better if you’re specifically interested in Java.

Good luck!

Thanks a lot, will take a look into those once I know more.
