Hi David,
all you need to do is run: java HelloCommandLineArguments (do not the use .class extension - that is what is causing the error) Regards, Dean Rush ----- Original Message ----- From: "David Seto" <[email protected]> To: [email protected] Sent: Monday, August 3, 2009 5:42:26 PM GMT -05:00 US/Canada Eastern Subject: RE: [java programming] Re: Lab 1038 Command Line Arguements got an error message Hi Dean This is what I did – Javac HelloCommandLineArguments.java to compile which worked fine. It created HelloCommandLineArguments.class I then typed in java HellocommandLineArguments.class Then I got the error message listed previously.

Hence you should run your program as: c:\myprograms>java HelloCommandLineArguments Regards, Babu On Sat, Aug 1, 2009 at 2:24 AM, David Seto < [email protected] > wrote: Ran the Example – public class HelloCommandLineArguments { public static void main( String[] args ){ // Print the string "Hello, " on screen System.out.println("I am saying Hello to the people below..
