java編寫背景音樂

import java.applet.audioclip;

import java.net.malformedurlexception;

import java.net.url;

import javax.swing.japplet;

public class playmusic {

public static audioclip loadsound(string filename) {

url url = null;

try {

url = new url("file:" + filename);

} catch (malformedurlexception e) {

}

return japplet.newaudioclip(url);

public void play() {

audioclip christmas = loadsound("music/bg.mp3");

christmas.play();

然後在主類中寫

playmusic p=new playmusic();

p.play();

那就行了，其中bg.mp3是存放在是music包下的要播放的音樂檔案
