I'm having issues with the following code:

package sdev425;

public class Sdev425 {

   /**

   public static void main(String[] args) {

       // Read the filename from the command line argument

       String filename = args[0];

       BufferedReader inputStream = null;

       String fileLine;

       try {

           inputStream = new BufferedReader(new FileReader(filename));

           System.out.println("Email Addresses:");

           // Read one Line using BufferedReader

           while ((fileLine = inputStream.readLine()) != null) {

               System.out.println(fileLine);

           }

       } catch (IOException io) {

           System.out.println("File IO exception" + io.getMessage());

       } finally {

           // Need another catch for closing

           // the streams         

           try {

               if (inputStream != null) {

                   inputStream.close();

               }

           } catch (IOException io) {

               System.out.println("Issue closing the Files" + io.getMessage());

           }

       }

   }

}

When running this code, without defining the .txt file for the argument I get the following output:

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

 at sdev425.Sdev425.main(Sdev425.java:23)

When running this code with the .txt file defined it lists the entire contents of the .txt file instead of what the code is created to do. The output is as follows:
