Can somebody help me with my Java code please? I'm really close!?

-I am trying to write a program that reads in text files and plays them as music notes. I have a folder that contains the text files named 'music' and when I run my program I have a JFileChooser that asks me which text file I would like to play. I select the file from the music folder, but regardless of which one I choose it only plays the first file: Ascale.txt. I know I have it hard coded in the main method but when I change that file name to one of the other files, my program only plays the Ascale.txt over and over. Here is my code:



import java.io.File;

import java.io.FileNotFoundException;

import java.util.Scanner;

import javax.swing.JFileChooser;



public class PlayThatTune {



public static double[] tone(double hz, double t) {

int sps = 44100;

int N = (int) (sps * t);

double[] a = new double[N+1];

for (int i = 0; i <= N; i++)

a[i] = Math.sin(2 * Math.PI * i * hz / sps);

return a;

}



public static double[] note(int p, double t) {

double hz = 440 * Math.pow(2, p / 12.0);

double[] a = tone(hz, t);

double[] hi = tone(2*hz, t);

double[] lo = tone(hz/2, t);

double[] h = sum(hi, lo, .5, .5);

return sum(a, h, .5, .5);

}



public static double[] sum(double[] a, double[] b, double awt, double bwt) {

//superpose a and b, weighted

double[]c = new double[a.length];

for(int i = 0; i < a.length; i++)

c[i] = a[i] * awt + b[i] * bwt;

return c;

}



public static void main(String[] args) throws FileNotFoundException {



//Create a file chooser

final JFileChooser fc = new JFileChooser(".");

fc.showOpenDialog(null);

getSelectedFile();



Scanner in = new Scanner(new File("music/Ascale.txt"));

// repeat as long as there are more tokens to read in

while (in.hasNext()) {

// read in the pitch, where 0 = concert A (above middle C)

int pitch = in.nextInt();

// read in duration in seconds

double duration = in.nextDouble();



// build sine wave with desired frequency

double hz = 440 * Math.pow(2, pitch / 12.0);

int N = (int) (StdAudioOut.SAMPLE_RATE * duration);

double[] a = new double[N+1];

for (int i = 0; i <= N; i++) {

a[i] = Math.sin(2 * Math.PI * i * hz / StdAudioOut.SAMPLE_RATE);

}



// play it using standard audio

StdAudioOut.play(a);

}

}



private static void getSelectedFile() {



}

}



I would appreciate any help!
