java做小游戏，怎么给游戏加背景音乐？？ 请附上代码，希望添加背景音乐代码能简短些!谢谢。。

Answer 1

//主程序部分

audioPlayWave = new myMusicPlay("1.wav");// 开音乐
audioPlayWave.start();
musicOpenLab = 1;
//音乐子类（都是苦命的孩子，要互利互惠啊）

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.FloatControl;
import javax.sound.sampled.LineUnavailableException;
import javax.sound.sampled.SourceDataLine;
import javax.sound.sampled.UnsupportedAudioFileException;

public class myMusicPlay extends Thread {
private String fileName;
private final int EXTERNAL_BUFFER_SIZE = 524288;

public myMusicPlay(String wavFile) {
this.fileName = wavFile;
}

public void run() {
File soundFile = new File(fileName); // 播放音乐的文件名
if (!soundFile.exists()) {
System.err.println("Wave file not found:" + fileName);
return;
}
while (true) { // 设置循环播放
AudioInputStream audioInputStream = null; // 创建音频输入流对象
try {
audioInputStream = AudioSystem.getAudioInputStream(soundFile); // 创建音频对象
} catch (UnsupportedAudioFileException e1) {
e1.printStackTrace();
return;
} catch (IOException e1) {
e1.printStackTrace();
return;
}
AudioFormat format = audioInputStream.getFormat(); // 音频格式
SourceDataLine auline = null; // 源数据线
DataLine.Info info = new DataLine.Info(SourceDataLine.class, format);
try {
auline = (SourceDataLine) AudioSystem.getLine(info);
auline.open(format);
} catch (LineUnavailableException e) {
e.printStackTrace();
return;
} catch (Exception e) {
e.printStackTrace();
return;
}
if (auline.isControlSupported(FloatControl.Type.PAN)) {
FloatControl pan = (FloatControl) auline
.getControl(FloatControl.Type.PAN);
}
auline.start();
int nBytesRead = 0;
byte[] abData = new byte[EXTERNAL_BUFFER_SIZE];
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();
}
}
}
}
