Which shell command returns Java's home path?

I'm aware of the *which* command but when I run it on Java, I get the following path: $ which java /bin/java What I'm looking for, I think, is the Java path I get when I run the following Maven command: $ mvn -version Apache Maven 3.6.3 Java version: 11.0.14.1, vendor: Ubuntu, runtime: /usr/lib/jvm/java-11-openjdk-amd64 Default locale: en, platform encoding: UTF-8 OS name: "linux", version: "5.13.0-1021-aws", arch: "amd64", family: "unix" Isn't the latter (/usr/lib/jvm/java-11-openjdk-amd64) the correct Java home path? If so, which command would directly return it? Running the *java version* command doesn't return any paths.
