We're forgetting lessons of the past, so I updated this blog with links to four blogs from Nikhil Nanivadekar that explain why the Map, Set, Bag, and Multimap types in #EclipseCollections are more memory-efficient than the alternatives available in standard #Java.

I was asked after the "Refactoring to #EclipseCollections" talk at dev2next 2025 whether there were any #OpenRewrite recipes for EC. My answer was "No, but it would be great if someone contributed some in OSS." Thanks Craig Motlin! 🙏 @zakhav @jitterted

#EclipseCollections had forEachWithIndex as a method for almost 20 years. It also has several other "WithIndex" methods available for developers today. Java developers don't have to move to Kotlin to enjoy forEachWithIndex. 🤷‍♂️

Merry Christmas! 🎄
Also, happy 10th Anniversary #EclipseCollections!

I always wanted an Eclipse Collections hat. My wife had two made for me with the EC logo. A triple surprise, since she didn't know that today was also the 10th anniversary of EC. (See reply for picture of hats).🙏

If you miss the opportunity today, there will be one more chance for $0 ECC Kindle book on New Years. 👇

RE: https://mastodon.social/@TheDonRaab/115713700736196874

If you haven't done so, go grab your copy. The book goes beyond Eclipse Collections, offering great ideas on how to categorise functions and documentation, how to build fluent, intuitive, testable, and easy-to-evolve APIs in the open and much more. It's filled with decades of knowledge absorbed by the author, from the early days of OOP and Smalltalk to modern, expressive functional/OO hybrid Java that would surprise even the most sceptical programmer.

I really enjoyed giving this talk last week at @dev2next with my friend and co-speaker @zakhav.

This is probably the longest blog I have ever written, and is the first time I can recall in quite a while doing a live refactoring as I wrote a blog.

Enjoy! 🙏

After 21 years of developing, using, teaching, collaborating, blogging, podcasting, writing a book about #EclipseCollections, one thing motivates me to keep going.

There are millions of #Java developers that don't know what they have been missing for 21 years. 🤔
