      (to execute the main class in a module)
  or java [options] <sourcefile> [args]
      (to execute a single source-file program)
 Arguments following the main class, source file, -jar <jarfile>,
 -m or --module <module>/<mainclass> are passed as the arguments to
 main class.
 where options include:
  -zero  to select the "zero" VM
  -cp <class search path of directories and zip/jar files>
  -classpath <class search path of directories and zip/jar files>
  --class-path <class search path of directories and zip/jar files>
         A : separated list of directories, JAR archives,
         and ZIP archives to search for class files.
  -p <module path>
  --module-path <module path>...
         A : separated list of directories, each directory
         is a directory of modules.
  --upgrade-module-path <module path>...
         A : separated list of directories, each directory
         is a directory of modules that replace upgradeable
         modules in the runtime image
  --add-modules <module name>[,<module name>...]
         root modules to resolve in addition to the initial module.
         <module name> can also be ALL-DEFAULT, ALL-SYSTEM,
         ALL-MODULE-PATH.
  --list-modules
         list observable modules and exit
  -d <module name>
  --describe-module <module name>
         describe a module and exit
  --dry-run   create VM and load main class but do not execute main method.
         The --dry-run option may be useful for validating the
         command-line options such as the module system configuration.
  --validate-modules
         validate all modules and exit
         The --validate-modules option may be useful for finding
         conflicts and other errors with modules on the module path.
  -D<name>=<value>
         set a system property
  -verbose:[class|module|gc|jni]
         enable verbose output
  -version   print product version to the error stream and exit
  --version   print product version to the output stream and exit
  -showversion print product version to the error stream and continue
  --show-version
         print product version to the output stream and continue
  --show-module-resolution
         show module resolution output during startup
  -? -h -help
         print this help message to the error stream
  --help    print this help message to the output stream
  -X      print help on extra options to the error stream
  --help-extra print help on extra options to the output stream
  -ea[:<packagename>...|:<classname>]

  -dsa | -disablesystemassertions
         disable system assertions
  -agentlib:<libname>[=<options>]
         load native agent library <libname>, e.g. -agentlib:jdwp
         see also -agentlib:jdwp=help
  -agentpath:<pathname>[=<options>]
         load native agent library by full pathname
  -javaagent:<jarpath>[=<options>]
         load Java programming language agent, see java.lang.instrument
  -splash:<imagepath>
         show splash screen with specified image
         HiDPI scaled images are automatically supported and used
         if available. The unscaled image filename, e.g. image.ext,
         should always be passed as the argument to the -splash option.
         The most appropriate scaled image provided will be picked up
         automatically.
         See the SplashScreen API documentation for more information
  @argument files
         one or more argument files containing options
  -disable-@files
         prevent further argument file expansion
  --enable-preview
