Hey guys!
Local named classes are actually valuable, and this video tells you why.
Thank you, Michael Simons, for sending your solution to the question I asked in episode 003 (https://youtu.be/HDjEcV1X4jI)!

Java Language Evolution
Hey guys! How’s it going?
This is not your dad’s Java anymore!
The Java programming language has changed massively since Java 7, after introduction of the keyword var, records, switch expressions, and many more syntax changes. Modern Java feels quite differently and allows new idioms. Time to look into the language changes of nearly one decade, to get an idea how to write modern code style, and to express your ideas more concise. Also, in future we will have even better means to express ourselfs in terms of syntax instead of terms of API or architecture: Valhalla and Loom will further move Java into a readable and well-performing language.
Stay safe and… Party on!

A VERY BAD Decision – The Two Minutes Tuesday 006
Hey guys!
Everybody does mistakes – even the Eclipse Foundation’s Jakarta EE Working Group.
They decided BY ACCIDENT that a contributor loses his committer state once his employer is not paying Working Group Membership Fees. That is nuts! But good news: They fixed their mistake already, so everybody can become a committer FOR FREE!

A tiny plug-in based CLI framework ontop of jCommander
It is still a very initial beta, but we are rather proud of it: Today we published the source code of our tiny CLI application framework built around the terrific jCommander and ServiceLoader. What our framework provides ontop of jCommander is: It has a launcher which finds plugins on the classpath, so you can write plug-in based externally extensible CLI commands (including sub-commands) in Java. We think it is pretty cool and would be happy if you try it out and provide some feedback: https://gitlab.com/quipsy/cli-framework 🙂

JAX-RS Done Right! (VIII. – Advanced Parameter Topics)
Hey guys! How’s it going?
In today’s episode of “JAX-RS Done Right!” we will look into more advanced parameter topics that help us to make our code look much cleaner and support separation of concerns. With the help of a parameter converter provider we will strip all parameter handling from our JAX-RS resource and deal solely with a “purified” domain object.
Code example can be found on Gitlab: https://gitlab.com/mkarg/jaxrs-done-right
