请问一下用Clip 接口音频数据回放前加载，是什么意思？

Question

想用Clip实现音频输出，该怎么实现？

Answer 1

import javax.sound.sampled.*;
import java.io.*;
import java.util.stream.Stream;public class SoundPlayer {
File file;
AudioInputStream stream;
AudioFormat format;
DataLine.Info info;
Clip clip;
SoundPlayer()
{

}
public void loadSound(String fileName)
{
file=new File(fileName);
try
{
stream =AudioSystem.getAudioInputStream(file);
}catch(UnsupportedAudioFileException ex)
{
}catch(IOException ex){}
format=stream.getFormat();
}
public void playSound()
{
info =new DataLine.Info(Clip.class,format);
try
{
clip=(Clip) AudioSystem.getLine(info);
}catch(LineUnavailableException ex){}
try
{
clip.open(stream);
}catch(LineUnavailableException ex){}
catch(IOException ex){}
clip.start();}
public static void main(String[]args)
{
SoundPlayer sound=new SoundPlayer();
sound.loadSound("G:\\FFOutput\\NeedYouNow.wav");
sound.playSound();
}
}
