The Java developer community was surveyed, with over 10,200 respondents sharing their experiences with the Java Development Kit (JDK) and platform. The majority of developers use Oracle JDK in production, followed by OpenJDK. Most applications are built using Java SE version 8, while a smaller portion have migrated to newer versions such as Java 9 or higher. There is still uncertainty about how to respond to the new release cadence, with nearly one-third of developers not knowing how they will handle it. The survey also found that Kotlin has surpassed Groovy and Scala in popularity among JVM languages, and most developers use Java for their main applications.
