/*
 * T01n24.java -- A very simple demonstration of how to access any
 * command-line arguments provided when the program was executed.
 * 
 * Recall that this is how to execute a Java application from the command line:
 *     $ java T01n24
 * If the user wants to supply some information for the program to use,
 * without having to wait for the program to prompt for it, it may be
 * possible to type the information after the program name on the command
 * line.  For example:
 *     $ java T01n24 a bouncy "string of stuff"
 * If the code is written to accept info in this manner, it can speed up
 * common functionality.  This isn't as useful in Java, given its Internet
 * focus, than in other languages that have more of a text I/O focus.
 *
 * UNIX command line utilities use this mechanism frequently.  Example:
 *     $ ls -l
 * For that matter, the string "T01n24" is actually a command-line
 * argument to Java.
