 "classname"

    The name of the class to be executed, enclosed in quotation
    marks. The classname parameter must be fully qualified by
    including its package in the name, for example:

    $ JAVA "java.lang.String"

    In this example, JAVA interprets the directory path to be
    [JAVA.LANG], and the file name of the class to be STRING.CLASS.

 args

    Arguments that are passed to the main method of the class.
