命令介绍

The java_home command returns a path suitable for setting the JAVA_HOME environment variable. It determines this path from the user’s preferred JVM based on configured environment variables. Additional constraints may be provided to filter the list of JVMs available. By default, if no constraints match the available list of JVMs, the default order is used. The path is printed to standard output.
