Consider having a class:

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

What happens if you run it: java Test *?

Answer: it prints out all the filenames in current directory.
