"Saving the planet, one Collector at a time."

I can't un-new the billions of Collector instances that were created since 2014, but I can share ideas and alternatives for the future. Thanks for reading! 🙏

Counting and Collecting Collectors

Zero-argument methods on Java Collectors should return static instances.

For folks who haven't looked at #EclipseCollections because they don't use the Eclipse IDE. Eclipse Collections (EC) and the Eclipse IDE are both independent projects at the Eclipse Foundation. 💡

Note: I created EC and have coded with IntelliJ for 24 years. 🙏

There are thousands of subtle design decisions we made in #EclipseCollections over the years. I write about them so folks have the benefit of being able to learn from them many years later. The methods with/without, withAll/withoutAll are interesting cases. 🙏

What if the add and remove methods in java.util.Collection had fluent counterparts?

Eclipse Collections has complements to add/remove that can be chained.

Many of us seem to be counting the days during these strange times. In this blog, you will learn how to count the days using #Java Streams and how to make the days count using #EclipseCollections.

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. 🤷‍♂️

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.
