Java netbeans commadline argument passed

Question

I pass the command line argument using Netbeans, but I get ArrayIndexOutOfBoundsException.

My code is:

public class CmdLineArgumentPassing

{

      public static void main(String args[])
      {        
         System.out.println("Count : " + args.length);

         System.out.println("i : "+args[0]);
      }
} 

Conclusion:

Count : 0

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0

Answer 1

Right-click on the project, select Properties, go to the Run page, add command line arguments.
