    Web Development with Java (#41)

    Web Development with Java (#41)

    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?

    Making Java Attractive for Beginners in Programming (#40)

    Making Java Attractive for Beginners in Programming (#40)

    “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 in the Cloud (#38)

    Java in the Cloud (#38)

    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.
