    The following should be sufficient information on how to undertake this task.
    Scanner.
    String.

    Check out the different methods available to you, especially nextLine() from Scanner and length() from String.

    Do not mark your posts as URGENT. Your time constraints are your problem not ours. You are not more important than anyone else seeking help. Many like me refuse to help people who scream URGENT at us, which hinders your chances of getting help not enhancing it.

    Since the requirement states using command line arguments, the Scanner class would not be needed.

    Here is an example of reading a command line argument:

    public class CommandLine {
     
    	/**
    	 * JavaProgrammingForums.com
    	 */
    	public static void main(String[] args) {
     
    		System.out.println(args[0]);
    	}
     
    }

    The first argument you give when compiling the code will be printed out. You can take it from there..

    What option are you talking about? You just added an annoying all-caps "URGENT" to the title. That's not an option, that's you being obnoxious. Follow that with a homework dump, and I'm surprised you got any help at all. You should be thanking them, not arguing about whether you should or should not be given the option to post annoying titles.

    That's fine, but then you followed up with a confrontational "why let me do this" when all that was said was that marking your threads as urgent annoys people and decreases your chances of getting help- which continuing with "debates" will certainly not fix. Best to say "okay got it", move on, and don't do it in the future.

    For more information, see the link in my signature on asking questions the smart way, especially the parts titled "Don't post homework questions", "Don't flag your question as URGENT, even if it is for you", and "Courtesy never hurts, and sometimes helps".
