Issue 318 - Getting Rid of Unused Warnings with _

We sometimes are forced by the Java language to declare variables that we never use, attracting the ire of the javac compiler. Since Java 22 we have a way to declare these as "unnamed" by using an underscore.

Issue 317 - Explicit vs Diagnostic GC

How many times have we seen programmers call System.gc() to "help the garbage collector"? Unfortunately far too often, with potentially terrible performance implications. In this newsletter we explore the explicit and the diagnostic GC and how we can force a GC, even if explicit GCs are disabled.

Issue 316 - Code Before super() - JEP 447

Java 22 preview allows us to write code before the call to super(). There are restrictions. We are not allowed to refer to "this" in any way. We thus cannot set fields before calling the superclass constructor. But what if the superclass constructor calls our methods? In this newsletter we explore a workaround using ThreadLocals.

Issue 315 - Random Newsletter

Classes java.util.Random and java.util.SplittableRandom didn't used to have a common ancestor, making it difficult to write methods that take either. This was finally fixed in Java 17. Let's have a look at some random Java topics together.

Issue 314 - Harnessing the Power of ChatGPT 4.0 From Java

A few years ago, the second oldest man in our village Chorafakia wrote a book about the history of our area. Only catch - it was in Cretan Greek. I tried to read it, but couldn't. Google Translate shrugged at the strange Cretan dialect. Then ChatGPT 4.0 came along, and we can interact with it directly from within Java. In this newsletter we have a look at how I was able to translate this masterpiece into four languages: English, German, Dutch and Slovak.
