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

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. 🤷‍♂️

So sánh Eclipse Collections và JDK Collections:

1. Bộ nhớ: Eclipse Collections tối ưu hơn nhờ hỗ trợ kiểu dữ liệu nguyên thủy (primitive), giúp giảm tiêu thụ RAM đáng kể so với JDK Collections.
2. Hiệu năng: Khả năng xử lý song song và lặp nhanh hơn trong nhiều trường hợp thực tế.
3. API: Cung cấp bộ API phong phú (Immutable, Mutable, BiMap, Multimap) giúp code gọn gàng, dễ đọc hơn Java Streams truyền thống.

Does your collections code still read like it's 2015?

"A decade feels like a very long month"

Merry Christmas! 🎄
Also, happy 10th Anniversary !

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. 👇

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.

My latest blog: Mind Maps Didn't Make Me Scroll

It only took me a few years to realize that mind maps could help me communicate the package design in the api and impl jars for the open source library. Lesson learned and shared. 🙏

My latest blog: Refactoring to with 25 at the Conference

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 , one thing motivates me to keep going.

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

If you know, then let them know. 🙏

Thanks to @TheDonRaab, I've just dug up my password and posted on Code Ranch (@coderanch) forum for the first time since 2018. It's brilliant to see at least one of my favourite forums still going strong in 2025.

If you're into Java, why not pay Code Ranch a visit, ask Don a question, and maybe win a copy of his latest book (Eclipse Collections Categorically) in the process?
