求java播放音乐mp3等格式的代码
亲们，我想要一个java程序写的调用windows自带的音乐播放器播放map3等格式的音乐，如果有可能的话swing做的播放器也可以，我在网上找了很多例子和代码，有的是乱码，有的不能实现，，现在头都炸了，，希望高手快快出来，帮帮我~！ --------------------编程问答-------------------- 要搞这方面。奉劝你先学学Win32 API. --------------------编程问答-------------------- http://code.google.com/p/yoyoplayer/ --------------------编程问答-------------------- Win32 API 是什么？我只是需要一段如何调用本地播放器播放音乐的代码就可以，能实现就行 --------------------编程问答-------------------- 这个。。我下载了一个，怎么全是jar？ --------------------编程问答-------------------- 我听歌用的播放器就是自己用java swing写的。我在百度网盘http://pan.baidu.com/share/link?shareid=110575&uk=2165635302放了一份，楼主可以先看下。我这个需要32位的java虚拟机，不支持64位java虚拟机。 --------------------编程问答-------------------- 需要告诉楼主的是，我按照自己的需求来写的 能放几种格式的音乐，当做只能放MP3吧 可以放放MPG等格式的视频。好吧。功能简单的我都想把回帖删了。。不说了。 --------------------编程问答--------------------import java.io.FileInputStream;

代码直接贴给你，以前做swing的植物大战僵尸用的
--------------------编程问答-------------------- 为嘛把代码弄过去会报错？还要建立类？ --------------------编程问答-------------------- 下载了，一个可执行文件，可是路径弄上去没反应哇？ --------------------编程问答--------------------
报错是要把构建路劲改一下，你用的是jre要改成jdk --------------------编程问答-------------------- import sun.audio.AudioStream;
import sun.audio.ContinuousAudioDataStream;
这个是在jdk里面的 --------------------编程问答-------------------- 找jdk目录lib目录下面有个rt.jar加进去就行了
--------------------编程问答--------------------
在dos下输入 java -jar 目下的的YOYOPlayer.jar --------------------编程问答-------------------- 好像只能播放wav格式的音频 --------------------编程问答-------------------- 那个路径是你MP3音乐所在的路径。 --------------------编程问答-------------------- 比方我的音乐在D:/music文件夹下 这样设置就行了 --------------------编程问答-------------------- 然后程序会扫描该文件夹，能够播放的音乐格式的文件会被加载并播放。 --------------------编程问答-------------------- 这个代码能播MP3
--------------------编程问答-------------------- 大神们 学习了 --------------------编程问答-------------------- 天啊，我都晕了~！亲们，晚上的时候我再试试，今天应该能结贴~
