Subject: [java programming] Re: Lab 1038 Command Line Arguements got an
error message
Sorry for the typo -
I meant I typed in Java HelloCommandLineArguements.java
It created the class.
Then typed in javac HelloCommandLineArguements.class
Then got the error message listed below
Exception in thread "main" java.lang.NoClassDefFoundError:
HelloCommandLineArguments/class

Hi David,
The name of your class is HelloCommandLineArguments and not
HelloCommandLine. Hence you should run your program as:
c:\myprograms>java HelloCommandLineArguments

Babu

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.. ");
// Check if a command line argument exists
if(args.length == 0)
System.exit(0);
// Display the arguments from the command line
for(int counter = 0; counter < args.length; counter++){
System.out.println("argument index " + counter + ": " +
args[counter]);
}
}
}
After running the javac that created the class then ran the java I got the
following results
C:\myjavafxprojects\1038_commandarguments\commandarguments\samples\HelloComm
andLineArguments\src>java HelloCommandLine
