复制代码 代码如下:
import java.io.file;

auline.start();
int nbytesread = 0;
//这是缓冲
byte[] abdata = new byte[512];

}
} catch (ioexception e) {
e.printstacktrace();
return;
} finally {
auline.drain();
auline.close();
}
}
}
下面是一个java播放声音的应用程序，可以单次播放声音、循环播放声音
musicpaly mymusicplay = new musicplay(getclass().getresource("/music/button.wav"));
mymusicplay.start();//播放一次
mymusicplay .stop();//停止
mymusicplay .continuousstart();//循环播放
mymusicplay .continuousstop();//停止
复制代码 代码如下:
// 文件名:muiscplay.java
import java.io.*;
import java.net.url;
import sun.audio.*;
/**

* @author wuhuiwen
* 播放音频文件，产生音效
*/
public class musicplay {
private audiostream as; //单次播放声音用
continuousaudiodatastream cas;//循环播放声音
// 构造函数
public musicplay(url url)
{
try {
//打开一个声音文件流作为输入
as = new audiostream (url.openstream());
} catch (filenotfoundexception e) {
// todo auto-generated catch block
e.printstacktrace();
} catch (ioexception e) {
// todo auto-generated catch block
e.printstacktrace();
}
}
// 一次播放 开始
public void start()
{
if( as==null ){
system.out.println("audiostream object is not created!");
return;
}else{

}
}
// 一次播放 停止
public void stop()
{

system.out.println("audiostream object is not created!");
return;
}else{

}
}
// 循环播放 开始
public void continuousstart()
{
// create audiodata source.
audiodata data = null;
try {

} catch (ioexception e) {
