Symmetric Sympathy in #EclipseCollections. Mutable, Immutable, Object, Primitive. All eight #Java primitive types supported. Avoid the boxing without the wait for Valhalla.
I used of() with the factories. If your preposition preference is with(), then go with() love. Both work. 👍

GS Collections was open sourced by Goldman Sachs 14 years ago. The 10th anniversary of #EclipseCollections first release @eclipse.org is in 4 days. If you're waiting for new Collections in #Java after 30 years, the wait continues, while EC continues to grow & evolve. 💗🦋

Java Streams are great but it’s time for better Java Collections
After 25 years, it’s time for Java to get a Collections upgrade.

I remember when GS Collections was downloaded ~20K times a month from Maven Central 10 years ago. At the end of 2025, we will celebrate 10 years of #EclipseCollections at the @eclipsefdn.bsky.social.

Thursday after #JavaOne, I saw @starbuxman.joshlong.com create a GraalVM Native Image with #EclipseCollections. I never tried before.
A reason some folks provided in the past for not using Eclipse Collections was jar file size. If you're using GraalVM Native Image, what reasons do you still have?

A simple Multimap and equivalent Map example I wrote today. I hope these examples will help anyone unfamiliar with the differences between these two types. The implementations of groupBy in #EclipseCollections or groupingBy in #Java, should be conceptually similar, but perhaps more obfuscated.
