--------------------编程问答-------------------- 应该使用javax.sound 播放 --------------------编程问答--------------------
audio.play()换成javax.sound（）？没有这个方法吧？ --------------------编程问答--------------------
javax.sound是Java音频开发方面的扩展包 --------------------编程问答-------------------- 应该使用javax.sound 播放 --------------------编程问答-------------------- F:/love.mid要放在当前工作目录。直接改为“love.mid”应该可以。 --------------------编程问答--------------------
请问如何添加javax.sound到源代码里啊？我还是不明白，请指教 --------------------编程问答--------------------
你指讲音乐love.mid放在MyEclipse安装目录里吗？不行哦 --------------------编程问答--------------------
