Command Line Argument Help

Code :

---

 
	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....

Code :

---

[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.

Instead of using indexVar as the index, start counting in your for-loop from indexVar. Also, if this is the method you want, you will probably want to check to see if args.length <= 2 because if you don't, only "hello " will get printed out.

Code :

---

for (int i = indexVar; i < args.length; i++)
     System.out.print(args[i] + " ");

Thank you very much.
