Programming java game - HELP PLEASE

HotP0pp3r

I am currently trying to programme a bank robbing game but I cant seem to get the sound working and could do with a little help. I have checked online for some pointers but havent found anything of interest yet...

Bare in mind that I have only started trying to learn java so I dont have much of a clue atm :P

This is the code I am using atm:

import java.io.*;
import java.net.URL;
import javax.sound.sampled.*;

public enum SoundEffect {
SHOOT("ar.wav"), // shooting
WALK("footsteps.wav"), // gong
MUSIC("antichrist.mp3"); // bullet

// Nested class for specifying volume
public static enum Volume {
MUTE, LOW, MEDIUM, HIGH
}

public static Volume volume = Volume.LOW;

// Each sound effect has its own clip, loaded with its own sound file.
private Clip clip;

// Constructor to construct each element of the enum with its own sound file.
SoundEffect(String soundFileName) {
try {
// Use URL (instead of File) to read from disk and JAR.
URL url = this.getClass().getClassLoader().getResource(soundFileName);
// Set up an audio input stream piped from the sound file.
AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(url);
// Get a clip resource.
clip = AudioSystem.getClip();
// Open audio clip and load samples from the audio input stream.
clip.open(audioInputStream);
} catch (UnsupportedAudioFileException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (LineUnavailableException e) {
e.printStackTrace();
}
}

// Play or Re-play the sound effect from the beginning, by rewinding.
public void play() {
if (volume != Volume.MUTE) {
if (clip.isRunning())
clip.stop(); // Stop the player if it is still running
clip.setFramePosition(0); // rewind to the beginning
clip.start(); // Start playing
}
}

// Optional static method to pre-load all the sound files.
static void init() {
values(); // calls the constructor for all the elements
}
}


import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

// Testing the SoundEffect enum in a Swing application
public class SoundEffectDemo extends JFrame {

// Constructor
public SoundEffectDemo() {
// Pre-load all the sound files
SoundEffect.init();
SoundEffect.volume = SoundEffect.Volume.LOW; // un-mute

// Set up UI components
Container cp = this.getContentPane();
cp.setLayout(new FlowLayout(FlowLayout.CENTER, 10, 10));
JButton btnSound1 = new JButton("Sound 1");
btnSound1.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
SoundEffect.EXPLODE.play();
}
});
cp.add(btnSound1);
JButton btnSound2 = new JButton("Sound 2");
btnSound2.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
SoundEffect.GONG.play();
}
});
cp.add(btnSound2);
JButton btnSound3 = new JButton("Sound 3");
btnSound3.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
SoundEffect.SHOOT.play();
}
});
cp.add(btnSound3);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setTitle("Test SoundEffct");
this.pack();
this.setVisible(true);
}

public static void main(String[] args) {
new SoundEffectDemo();
}
}

Any useful comments would be much appreciated.

I understand the drive to do it all from scratch, especially for the sake of learning, but have you considered using some kind of game class library?
It takes care of a lot of the laborious stuff and leaves you with a more convenient code interface. It also provides a good structure for managing game objects.
Once you can jump past the basic foundations of the engine, you can actually focus on making the game, which is still a tonne of work, but you get right into the interesting/rewarding part, which (IMO) is seeing the game start to come together.
