java播放声音类和一个简单示例

播放声音的类

import java.io.file;
import java.io.ioexception;

import javax.sound.sampled.audioformat;
import javax.sound.sampled.audioinputstream;
import javax.sound.sampled.audiosystem;
import javax.sound.sampled.dataline;
import javax.sound.sampled.sourcedataline;

//播放声音的类
public class playsounds extends thread {

 private string filename;
 public playsounds(string wavfile) {

  filename = system.getproperty("user.dir")+wavfile;
 }
 public void run() {

  file soundfile = new file(filename);

  audioinputstream audioinputstream = null;
  try {
   audioinputstream = audiosystem.getaudioinputstream(soundfile);
  } catch (exception e1) {
   e1.printstacktrace();
   return;
  }
  audioformat format = audioinputstream.getformat();
  sourcedataline auline = null;
  dataline.info info = new dataline.info(sourcedataline.class, format);
  try {
   auline = (sourcedataline) audiosystem.getline(info);
   auline.open(format);
  } catch (exception e) {
   e.printstacktrace();
   return;
  }
  auline.start();
  int nbytesread = 0;
  //这是缓冲
  byte[] abdata = new byte[512];
  try {
   while (nbytesread != -1) {
    nbytesread = audioinputstream.read(abdata, 0, abdata.length);
    if (nbytesread >= 0)
     auline.write(abdata, 0, nbytesread);
   }
  } 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

// 文件名:muiscplay.java
import java.io.*;
import java.net.url;
import sun.audio.*;
