What's This?

Picking a popular technology makes our developer life easier. My free, quarterly newsletter measures Java technology popularity by following the money: job ads in 59 countries and online course purchases by 60+ million developers. It also analyzes developer interest with Google searches and developer engagement with questions at Stack Overflow.

Updates for Q1/2024: Developer job ads down 32% year over year, Stack Overflow questions dropped 55% since ChatGPT. I now recommend IntelliJ Community Edition because many AI code assistants don't run in Eclipse. Job ads for Quarkus hit an all-time high.
The Java technologies are: IDEs, build tools, JVM languages, databases, back-end frameworks, web frameworks, and mobile app frameworks. I also recommend options in each of these seven areas. My recommendations are based on that popularity, industry analysis, and my 25 years of Java experience.
Why popularity? Because popular technologies are easier to learn, build, debug & deploy, easier to find jobs/hire, and easier to convince teammates & bosses. Popularity can make a difference in two situations: When multiple technologies score similarly, we could go for the most popular one. And when a technology is very unpopular, we may not use it.
