Really? Java developers love writing non-Java

What language do Java developers love to write in? The results of a survey of 100 Java developers may surprise you

I asked -- and the people responded! Fun fact No. 1: Apparently only 28 percent of Java developers write Java full time.

My survey may not be a truly scientific poll, but I was able to grab a good sampling of folks in the Java group on Google+ along with people in my Twitter, LinkedIn, and Facebook networks. Many of those folks in turn retweeted and reposted, so I actually know a only few of the people who responded. Throwing out duplicates and errors didn’t significantly affect the results.

How do these responses track with your experiences? I'd love to know.

Are you still doing exclusively Java?

  Respondents Percentage
Yes, only Java 27 27%
No, mix of Java and other things 72 73%

What other JVM languages are you using?

  Respondents Percentage
Groovy 38 32%
Scala 24 21%
JavaScript (Rhino/Nashorn) 21 18%
JRuby 9 8%
Jython 7 6%
PHP (Quercus, etc.) 6 5%
Clojure 6 5%
Other 5 4%
Erjang 1 1%
OCaml 0 0%

What surprised me is that at 33 percent, Groovy was the top JVM language. I had expected Scala, which came in second at 20 percent, to rule the roost. Note: The numbers don't add up to 100 percent because developers could and did pick multiple languages.
