Java programs require a Java Virtual Machine (JVM) platform to run. Over time, alternatives to the Java programming language have been developed that can run on a single JVM, these include Clojure, Scala, Groovy, and Kotlin. All these languages are available for Arm.


Commercial

OpenJDK implementations are available from popular vendors including Red Hat, Ubuntu, SUSE, Azul, and others. Arm is a big contributor to OpenJDK, which ensures excellent performance on AArch64 platforms.

Library ecosystem

The Java library ecosystem is very mature. With a continued investment from Arm and the community, developers can include one or more of the tens-of-thousands of open-source libraries and be confident that they will work on AArch64. Arm continues to work with the community to ensure libraries work best on AArch64.
