Java 8 Survey: The Results Are In

Typesafe ran a survey of Java developers in February, along with a follow-up in September - you might have seen that one on DZone - and together they present an interesting look at the uptake of Java 8 and other industry trends.

The first part of the survey focused on Java 8, looking at plans to upgrade and thoughts on major additions, such as a lambdas, while the second part explored developers' opinions on Java and industry trends in general. The survey results provided some interesting insights. For example:

  • In the original survey, about half of developers surveyed planned to upgrade within two years, but by the time the follow-up came around (six months later), 27% had already upgraded, and an additional 36% planned to upgrade within a year.
  • 45% of surveyed developers are already using Java 8's Lambdas 
  • Among surveyed developers who are not using Java 8, 69% are using Java 7 in production, while 26% are using Java 6.

Other results explore questions such as the impact of Java 8's Lambdas on Scala adoption, the obstacles that prevent developers/organizations from upgrading, interest and hopes for Java 9, the most popular technologies in the Java developer's "stack," Big Data and IoT interest and adoption, and more. 

One particularly interesting question maps out the technologies developers use in their production infrastructure, covering everything from Hadoop and Spark to Docker and OpenStack - Amazon EC2 leads this list by a wide margin. 

Check out the full results from Typesafe for all the details. It's a pretty complete industry breakdown if you're wondering what other Java developers think and, more importantly, what technologies they're working with.
