java编写添加背景⾳乐代码_java代码中简单添加背景⾳乐（亲
测有效）
在做java贪吃蛇游戏课设时，想添加背景⾳乐，⽤了以下很简单的步骤即可完成，亲测有效哦！威宁县
调⽤⽅法：
new Thread(()->{while(true) {Data.playMusic();}秦朝灭亡时间
}).start();// Lambda表达式
//new Thread(new Runnable() {
//
//@Override
//public void run() {
//while (true) {
/
/playMusic();
//}
//}冷与热
//}).start();// 开启⼀个线程⽤来播放⾳乐
⽅法体：
import java.io.File;
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.SourceDataLine;
扈华国static void playMusic() {// 背景⾳乐播放
try {
AudioInputStream ais = AudioInputStream(new File("D:/mysoft/eclip/贪吃蛇/music.wav")); //绝对路径AudioFormat aif = Format();
final SourceDataLine sdl;
DataLine.Info info = new DataLine.Info(SourceDataLine.class, aif);
sdl = (SourceDataLine) Line(info);
周末愉快英语>查看内存条型号sdl.open(aif);
sdl.start();
FloatControl fc = (FloatControl) Control(FloatControl.Type.MASTER_GAIN);
// value可以⽤来设置⾳量，从0-2.0
double value = 2;什么牛什么虎
延安我把你追寻
float dB = (float) (Math.log(value == 0.0 ? 0.0001 : value) / Math.log(10.0) * 20.0);
fc.tValue(dB);
int nByte = 0;
final int SIZE = 1024 * 64;
byte[] buffer = new byte[SIZE];
while (nByte != -1) {
nByte = ad(buffer, 0, SIZE);
sdl.write(buffer, 0, nByte);
}
sdl.stop();
} catch (Exception e) {
e.printStackTrace();
}
}
注意事项：
若程序报错：
Exception in thread "main" javax.sound.sampled.UnsupportedAudioFileException: could not get audio input stream from input file
at javax.sound.AudioInputStream(AudioSystem.java:1189)
at com.ywq3.Test.main(Test.java:21)
