How to Build Java Applications Today?

I Help You Answer This Question

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. I also analyze developer interest with Google searches and developer engagement with questions at Stack Overflow.

Java Tech Popularity Index Q3/2023 (September 17, 2023)

Read the index to see all scorecards, all details & my recommendations. Below’s a sneek peak.

Data updates for Q3/2023: The number of developer ads is down in 2023 by about 25%. Spring Boot is back to 500% of Jakarta EE job ads, while Quarkus and Micronaut rose again after a four-month decline. The monthly number of Stack Overflow questions is down 42% since ChatGPT appeared.

I use scorecards show the current standings & trends of the top three technologies in each area. The number 2 is at 100%, but not on the card. The leader (left) and number 3 (right) are. The red arrows show the trend vs. the number 2. Below are two examples.

How does Java hold up against its competition? Here are Python (left) and Java (right) vs. JavaScript (100%) (not on the card). The arrows show the trend vs. JavaScript.

Python slightly declines in jobs against JavaScript but holds steady or slightly increases in all other categories. Java gains slightly in jobs against JavaScript and declines slightly everywhere else.

And what about back-end frameworks? Here is Spring Boot (left) and and Quarkus (right) vs. Jakarta EE (100%), not on the card. The arrows show the trend vs. Jakarta EE.

Spring Boot pulls away from Jakarta EE everywhere except for job ad mentions. Quarkus gains on Jakarta EE everywhere.
