Occasionally, I discover a developer complaining about the verbosity of #Java Streams. 😮‍💨

We spent 21 years tackling the verbosity and other challenges with Java collections, and incidentally solving many of the verbosity issues with Java Stream. 🏋️

Q: Is the Eclipse IDE required to use Eclipse Collections?
A: No. Eclipse Collections is a stand-alone Java library and one of many open source projects at the Eclipse Foundation.

I was asked again yesterday, and responded w/ the branding section of this blog.👇🙏

I answered the question "How do you learn a rich API?" a couple of weeks ago in a Pittsburgh JUG meetup. I wrote the book "Eclipse Collections Categorically" to show how any developer can solve this problem.

The path to learning is right in front of you. 👣
