How to Build Java Applications Today #65


I cover IDEs & build tools, I measure Java's popularity vs. non-JVM languages, Scala beats Kotlin in job ad mentions, Spring Data MongoDB vulnerability, Kotlin roadmap, Stack Overflow Developer Survey 2022.


Welcome to my newsletter “How To Build Java Applications Today”! If you like it, then subscribe to it on Substack! Or read it on or Medium. Even better: Share it with people who are interested!


I now cover IDEs & build tools, I also measure the popularity of Java vs. Python, JavaScript, C#, and Go, and the Technology Index will only be updated quarterly now.

Technology Index

I recommend IDEs, build tools, JVM languages, databases, back-end frameworks, web frameworks, and mobile app frameworks. This report is different because it measures popularity by observing all Java developers: job ads from 62 countries, online training students, Stack Overflow questions, and Google searches. My recommendations are based on that popularity, industry analysis, and my 23 years of Java experience.

Popularity trends in job ad mentions: Scala surpassed Kotlin. All databases lost to Postgres last month. Quarkus is number three after DropWizard’s collapse. And everybody lost to the mobile app framework Flutter.

Release Radar

Eclipse, NetBeans, and VS Code had major releases in June 2022, as did Git and Quarkus. Maven, Spring Boot, Quarkus, Micronaut, DropWizard, and IntelliJ had minor ones.
