How to identify installed Java (JDK) Version on macOS


If you have just updated your macOS and want to know what version of Java you have already, the easiest way is to check the java version using the terminal.

$ java -version

$  java -version
java version "11"
Java(TM) SE Runtime Environment (build 11)
Java HotSpot(TM) 64-Bit Server VM (build 23.2-b04, mixed mode)

If you have multiple JDK installed you can find them under /Library/Java/JavaVirtualMachines directory.

To run a specific version of Java on macOS you can make use of JAVA_HOME,

Example:

$ /usr/libexec/java_home -v 15 --exec javac -version
