certification
In the summer of 2021, I got my Java 11 certification. I expected it to be quite a breeze, because I’d been a Java developer for 14 years and surely I should have seen it all by now, right? Turned out I was very wrong. I came across lots of things that I didn’t even know were possible with Java. In this weekly blog series I will go through 11 of these ‘crazy learnings’ that surprised me the most, even as an experienced developer. The final ‘crazy learning’ I’ll be blogging about has to do with method references.

conference
Here’s your chance to share your knowledge about Java, the JVM and all its offshoots, side alleys, traps, pitfalls, amazing capabilities and history. Know a cool fact about Kotlin? Got the low down on what colour James Gosling’s car was when he invented Java? Can you explain how to use caching in Spring?

pattern-matching
We’ve known lambdas and streams since Java 8, and they’ve made Java a more powerful language. In the next few versions of Java, even more features that originated in functional languages will be added, one of which is pattern matching. It provides an elegant way to apply conditions to certain aspects of an object. We set out to investigate the possibilities that were introduced in JEP 305 (‘Pattern Matching for instanceof’) and how the pattern matching roadmap will make Java an even more powerful language.

Today is Java’s 25th birthday! On the 23rd of May 1995 the language was introduced at the SunWorld conference, in a time where desktop applications reigned supreme and the internet was still in its infancy.
