I have just implemented my very first sound "engine" for my game and did it probably very messily because I don't know a whole lot about sounds and Java. Anyways, I have this class:

| package Engine;
public class Sounds {
public static String explosion = "explosion.wav";
public static String inGameMusic = "inGameMusic.wav";
} |
which holds all the names for my game. My problem is, whenever I call a sound, namely the explosion because that's the only one I have right now, the game freezes for the duration of the sound, and then continues when the sound is done. I think this definitely has something to do with Threads, but I am not confident in that area at all either so should I multi-thread, one for the game, and one for the sounds and if so, how?
Thanks,
