Most of us are simple users of OSS (Open-source software) but being brave and taking a step forward and becoming a contributor, or even an owner, could help you massively in different ways: Collaborating with clever people ...

Java 8 Streams: filter and predicate negation

java-logo

Recently there was an interesting discussion on the use of predicate negation in the .filter method on a stream by members of the LJC mailing list, so I thought it would be worth summarising it in a blog post. The discussion was about ways to use .filter and to negate the predicate. Code for this post is available in my ...

jboss-drools-logo

A few months ago we started redesigning the Drools lowest level executable model and making it accessible to end user with a Java 8 API.

Tell, don’t ask

Eclipse IDE on JDK 9 Early Access with Project Jigsaw

eclipse-logo

I wrote a few weeks ago about getting Eclipse Neon running on Java 9 (though, I had mistakenly and embarrassingly left “Mars” in the title of the post). It’s worth noting that the steps that I laid out also apply to the JDK 9 Early Access with Project Jigsaw (Java modularity) builds. Eclipse Neon works on Jigsaw. I’ve been using this combination for real development ...

Emotion-Based Computing: What It Is and How You Can Benefit

From Arrays to Streams and Back with Java 8

java-logo

Not long ago we upgraded some Eclipse plug-in projects to Java 8. And never looked back since. Among many other things, filtering, mapping, and finding elements in collections has become so much easier and more concise with lambdas and the streams API. Nothing new so far for the most of you, I guess. But many existing APIs use arrays in ...
