Need a little help with sound in a JApplet
- by jacob schuschel
I am working on a solitaire game in Java, and i need to implement sound when the desk is shuffled, card flipped, etc. I used the following sites as reference to try and get it to work, but i am getting Null Pointer Exceptions or mishandled URL exception (depending on what i tweak).
here
Also, i am using netbeans 6.7.1 as my IDE.
I will try to break down the code and explain:
package cardgame;
import java.applet.*;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.swing.JApplet;
import javax.swing.*;
import java.io.*;
import java.net.*;
/**

public class Sound extends JApplet {
private AudioClip song; // Sound player
private String URL = null;
private URL songPath; // Sound path
/*
*sound_1 = shuffling cards
*sound_2 = to discard
*sound_3 = from discard
*sound_4 = cardflip 1
*sound_5 = cardflip 2
*/
Sound(String filename) {
try {
songPath = new URL(getCodeBase(),filename); // Get the Sound URL
} catch (MalformedURLException ex) {
Logger.getLogger(Sound.class.getName()).log(Level.SEVERE, null, ex);
}
song = getAudioClip(songPath); // Load the Sound
}
Sound(int i) {
URL = "./sounds/sound_" + i + ".wav";
System.out.println(URL);
try {
songPath = new URL(URL); // Get the Sound URL
song = getAudioClip(songPath);
} catch (MalformedURLException ex) {
Logger.getLogger(Sound.class.getName()).log(Level.SEVERE, null, ex);
}
}
public void playSound() {
song.loop(); // Play
}
public void stopSound() {
song.stop(); // Stop
}
public void playSoundOnce() {
song.play(); // Play only once
}
}
The 2 different construcors are for different ways i tried to implement this. The first one creates the filepath, and passes it in. The second one builds the filepath in the constructor, given a sound # (i made a list of what numbers correspond to what sound for reference). I am getting the followig errors out:

Thanks for those who read and more thanks to those who help. I know it is somewhat long, but i would rather get it all out there, than have 50 questions that come back or have people not answer due to lack of initial info. also only lets me post a single link right now, so the links are given below
