Foojay.io | Friends of OpenJDK and Java Programming

Once a month in this podcast, we talk about the history of a Java User Group and the people behind it. We have a special group in this episode as we visit the virtual Quarkus Club. This initiative started less than a year ago and is already one of the biggest groups in the world dedicated to Quarkus.

When starting to build a new website, you are facing a major challenge. Which framework should you use? Angular, React, Vue, Svelte? They are all based on JavaScript and can be the right choice depending on your needs. But do you really need one of these frameworks? Why would you not just stick to Java and use one of the many great libraries that are available for it?

“Public static void main string array” are the first words everyone sees when they start their first Java Hello World experiments. Some teachers explain them, while others say you will understand each word later.

Is this a problem to attract more Java developers? And how can we make the Java language more attractive for newbies? Let’s ask some experts…

Java was born in 1995, when the internet as we know it today, didn’t exist yet. Cloud servers, Docker, Kubernetes, distributed systems, scaling up and down,… These things are now part of our daily job, but Java wasn’t originally designed for it. In this episode, we want to learn if the recent evolutions in OpenJDK, and ongoing related projects, will make Java a full Cloud member.

Check the previous Foojay Podcasts for the first three parts of our J-Fall report. That one-day conference in the Netherlands in November was packed with amazing sessions. In this episode, you’ll get the remaining interviews we made that day. And as they say, last but not least, again, we have some fascinating insights for you into Java and its evolutions.

In Episodes 33 and 34 of the Foojay Podcast, you got the first two parts of our JFall Report. But on that single-day conference, we had many more interesting interviews, so this is part 3! Later, we will talk about JOOQ, Desktop Applications, and Security. But first… Maven. It’s one of the most used tools in Java development, and we can learn a lot from different experts who joined me for an interview. Let’s start with Ixchel, who gave both a workshop and a talk.
