How do I fix this error?

import hsa.Console;

import java.io.IOException;

import javax.sound.sampled.AudioInputStream;

import javax.sound.sampled.AudioSystem;

public static void main (String[] args)

{

c = new Console ();

sound ();

} // main method

public static void sound ()

try

{

AudioInputStream audio;

audio = AudioSystem.getAudioInputStream (this.getClass ().getResource ("Deal Or No Deal Full Theme Song.wav"));

javax.sound.sampled.Clip clip = AudioSystem.getAudioInputStream (java.io.File $1);

clip.open (audio);

clip.start ();

}

catch (UnsupportedAudioFileException uae)

I am working with Ready To Program with Java. I am using HSA consoles. Everything seems to be working except one line:

javax.sound.sampled.Clip clip = AudioSystem.getAudioInputStream (java.io.File $1);

where the program is giving me an error with "$1" (it is highlighting only the "$1"). There are no other errors in the program. I am trying to get sound to play when I run the program.
