Thread: Command Line Argument Help

 
	if(args.length <= 0)
            System.out.print("Hello World");
 
	else if (args.length > 0)			
         {
            System.out.print("Hello ");
            for (int i = 0; i < args.length; i++)
               System.out.print(args[i] + " ");
 
         }
	System.out.println();

(A little background, all I'm doing is replacing "world" if there are command line arguments, with those args)


How would I, using a variable that has the index of the 2nd passed data argument, with passing in a comm. line arg. such as "java Hello arg1 arg2 arg3 arg4" get the output of "Hello arg3 arg4"?

Whenever I add in this variable....

[COLOR="Red"]int indexVar = 2;[/COLOR]
 
if(args.length <= 0)
            System.out.print("Hello World");
 
	else if (args.length > 0)			
         {
            System.out.print("Hello ");
            for (int i = 0; i < args.length; i++)
               System.out.print(args[[COLOR="Red"]indexVar[/COLOR]] + " ");
 
         }
	System.out.println()

I get the output of Hello arg3 arg3 arg3 arg3.
I am assuming this is happening because the for loop is looping system.out for the args length which is 4. But I don't know how to fix that, and keep getting that unwanted output.

Can you guys be of some help? Thanks.

Thank you very much.
