Java编程实现获取mp3时长及播放mp3文件的方法

import java.io.BufferedInputStream;import java.io.File;import java.io.FileInputStream;import org.jaudiotagger.audio.AudioFileIO;import org.jaudiotagger.audio.mp3.MP3AudioHeader;import org.jaudiotagger.audio.mp3.MP3File;import javazoom.jl.player.Player;public class MusicUtil { public static void play(String position) {  try {   BufferedInputStream buffer = new BufferedInputStream(new FileInputStream(position));   Player player = new Player(buffer);   player.play();  } catch (Exception e) {   e.printStackTrace();  } } public static int getDuration(String position) {  int length = 0;  try {   MP3File mp3File = (MP3File) AudioFileIO.read(new File(position));   MP3AudioHeader audioHeader = (MP3AudioHeader) mp3File.getAudioHeader();   // 单位为秒   length = audioHeader.getTrackLength();   return length;  } catch (Exception e) {   e.printStackTrace();  }  return length; } public static void main(String[] args) {  String position = "逃跑计划-夜空中最亮的星.mp3";  getDuration(position);  play(position); }}
