Since Java 11 there is no separate JRE for Oracle and OpenJDK java distributions.

There is only JDK. And JDK has everything that JRE has. So in your case you have Java 12 JDK.

You have Java installed with the JDK kit. You wouldn't be getting that output otherwise.

If you are on an older version, just type java. That works too

You can type jshell in the terminal.

Or just try typing jdb. Both will tell you about whether jdk is present or not.
