java播放mp3格式音乐_java播放mp3格式音频文件

下载完成之后解压提取jl1.0.0.1.jar

这里写图片描述

将jl1.0.0.1.jar拷贝到项目中&＃xff0c;并添加到Library

这里写图片描述

4.源代码

//Tip: 由于工程名和包名不一样&＃xff0c;最好手打不要盲目复制

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;

//构造方法 参数是一个.mp3音频文件

public AudioPlayer(File file) {

this.music &＃61; file;

}

//播放方法

public void play() throws FileNotFoundException, JavaLayerException {

BufferedInputStream buffer &＃61; new BufferedInputStream(new FileInputStream(music));

player &＃61; new Player(buffer);

player.play();

}

}

5.如果想把音乐播放作为其他程序的背景音乐&＃xff0c;则可以让其继承Thread&＃xff0c;代码如下&＃xff1a;

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.*;

/***

*/

//继承自线程类Thread

public class AudioPlayer extends Thread{

Player player;

File music;

//构造方法

public AudioPlayer(File file) {

this.music &＃61; file;

}

//重写run方法

&＃64;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 &＃61;

new BufferedInputStream(new FileInputStream(music));

player &＃61; new Player(buffer);

player.play();

}

}
