1. 下載完成之後解壓提取jl1.0.0.1.jar
   
2. 將jl1.0.0.1.jar拷貝到專案中，並新增到Library
   
   4.原始碼

//Tip: 由於工程名和包名不一樣，最好手打不要盲目複製

package com.lt.music;
import java.io.BufferedInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;

import javazoom.jl.decoder.JavaLayerException;
import
 
 javazoom.jl.player.*;
/***

public class AudioPlayer{
    Player player;
    File music;
    //構造方法  引數是一個.mp3音訊檔案
    public AudioPlayer(File file) {
        this.music = file;
    }
    //播放方法
    public void play() throws FileNotFoundException, JavaLayerException {

            BufferedInputStream buffer = new
 
 BufferedInputStream(new FileInputStream(music));
            player = new Player(buffer);
            player.play();
    }
}

5.如果想把音樂播放作為其他程式的背景音樂，則可以讓其繼承Thread，程式碼如下：

package com.lt.music;
import java.io.BufferedInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;

import
 
 javazoom.jl.decoder.JavaLayerException;
import javazoom.jl.player.*;
/***
 * 音樂播放器類
 * @author lt
 *  time 2016-7-5
 */
 //繼承自執行緒類Thread
public class AudioPlayer extends Thread{
    Player player;
    File music;
    //構造方法
    public AudioPlayer(File file) {
        this.music = file;
    }
    //重寫run方法
    @Override
    public void run() {
        super.run();
        try {
            play();     
        } catch (FileNotFoundException | JavaLayerException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
    //播放方法
    public void play() throws FileNotFoundException, JavaLayerException {

            BufferedInputStream buffer =
                    new BufferedInputStream(new FileInputStream(music));
            player = new Player(buffer);
            player.play();
    }
}
