Eclipse Collections is an Open Source Java Collections library with 16+ years in the making. As we start this new year 2021, many feelings come to mind. I started my Open Source journey in 2020 by contributing to Eclipse Collections. In November 2020, I was elected as a committer. I am filled with gratitude and humility for having being given this opportunity, platform, and more importantly, support and kindness from the Eclipse Collections team.

We at Eclipse Collections are thankful to all our contributors and supporters who played an integral role in keeping this Open Source library vibrant and successful.

Eclipse Collections has a rich assortment of data structures, and one of them is a Set. Recently, I worked on an issue to implement union, intersect and difference operations in sets for primitive types.

The next few sections will cover each operation’s objective, design considerations, and code implementation. The last section will cover the takeaways.

Union — What does this operation do?

Method signature: setA.union(setB)

union as the name indicates, it takes elements from two sets and combines them into one.

Ever since Java announced their 6-month release cycle, there is excitement around exploring new features and even more so with preview features.

It is available in a JDK feature release to provoke developer feedback based on real world use; this may lead to it becoming permanent in a future Java SE Platform.

One such noteworthy preview feature called “Records” was introduced as part of Java 14 in March 2020. …

50 Open Source Contributions in 2020!

It may not seem like a lot. In fact, the contributions themselves were pretty minor. But to me, it is 50 times or more I stayed away from Netflix, Youtube, and the likes to work on an Open Source project. Don’t get me wrong, I have binge-watched a couple of TV shows these past few months. But I can say with certainty that working on an Open Source project is just as fun as binge-watching a full season of Stranger Things.

Working on an Open Source project was a personal goal of mine. My motivations were to explore a different style of learning that allows me to apply new technologies to real projects and pursue a hobby that is both fun and challenging. If you are someone who, like me, aspires to contribute to Open Source projects, I have highlighted some of my personal experiences below. Hopefully, these will help you understand how some of my initial inhibitions became positive experiences. …
