Command-Line Arguments in NetBeans

I have a problem in NetBeans with Command-Line Arguments, when run this code it says 

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

Note I put an argument in command line for NetBeans 

public class NewEmpty1
{
  public static void main(String arg[]){
   System.out.println(arg[0]);
  }
}

What is wrong ?

public class NewMain {
    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        int argslen=args.length;
        int argsValue[] = new int[argslen];
        for (String i:args) {
           int d = 0;
           argsValue[d]=Integer.parseInt(i);
           System.out.print(argsValue[d]+"\t"+"\n");
        }
    }
}

goto Project-Property-Run here you will see the option main class arguments

now make sure you are accessing the correct main class....after this option you have button to browse the class path. select it and then select the arguments finally you should be able to run the program...cheers!

subscript the string beyond its index is undefined.

this is your case. args[] is empty.

You have not passed any arguments..

And if you have passed arguments then it may be because you are invoking another class main method in the same package

the best way would be to iterate..

for(string s:arg)
     System.out.println(s);

or

for(int i=0;i<arg.length();i++)
    System.out.println(arg[i]);
