Sounds like your code is bad.

No, I cannot. I see none of your code and subsequently I cannont help you.

Here is a working example of accepting command line arguments. It uses Java 5 Enhanced For Loop to iterate the array of strings.

 java Syntax (Toggle Plain Text) 
import java.io.*;
 
public class PrintArgs 
{
	public static void main(String[] args) 
	{
		System.out.println("This is stuff you entered: \n");
 
		for(String myString: args)
		{
			System.out.println(myString);
		}
 
		System.out.println("\nEnd of stuff you entered.");
	}
}
import java.io.*;

public class PrintArgs 
{
	public static void main(String[] args) 
	{
		System.out.println("This is stuff you entered: \n");
		
		for(String myString: args)
		{
			System.out.println(myString);
		}
		
		System.out.println("\nEnd of stuff you entered.");
	}
}

C:\>javac PrintArgs.java

C:\>java PrintArgs arg0 arg1 arg2 yar-harg
This is stuff you entered:

arg0
arg1
arg2
yar-harg

End of stuff you entered.

thanks for the reply mrynit.
This is the error I get after I copy and past your code into a new netbeans class

init:
deps-jar:
Compiling 1 source file to C:\Users\admin\Documents\NetBeansProjects\JavaNode\build\classes
javac: invalid flag: 1
Usage: javac <options> <source files>
use -help for a list of possible options
BUILD FAILED (total time: 0 seconds

f1 help doesn't do much.

here is code I wrote and tried to run:

public class NewClass {
public static void main (String[]args)

{System.out.println("hi" + args[0]);}

}

and I get this error:

init:
deps-jar:
Compiling 1 source file to C:\Users\azhari\Documents\NetBeansProjects\JavaNode\build\classes
javac: invalid flag: 1
Usage: javac <options> <source files>
use -help for a list of possible options
BUILD FAILED (total time: 0 seconds)

do you know how to pass arguments via any other enviornment e.g. j-creater, eclise etc?
