There can be multiple JDKs installed on the macOS system.

java -version in a Terminal window. If the installed version is 12 Interim 0, Update 0, and Patch 0, then you see a string that includes the text 12 . For example:
To run a different version of Java, either specify the full path, or use the
java_home tool. For example:
$ /usr/libexec/java_home -v 12 --exec javac -version

.dmg file if you want to save disk space.
