It looks like you are not passing anything in the command line argument.

To get the arguments you need to run your program as in the below example.

Java MyPrgm arg1 arg2 arg3 arg4

Now in main you can loop through the command line argument array and get the arguments

public static void main(String args[])
{
    for (int i = 0; i < args.length; i++)
      System.out.println(args[i]);
}

Check this for more information.
