音乐播放器课程设计java

Ⅰ 有大神可以做java编写的mp3音乐播放器的毕业设计 吗

http://wenku..com/link?url=_x3不用谢

Ⅱ java大神求解啊，如何用java编写一个音乐播放器，然后播放器里面的歌可以顺序播放的。

参考代码如下
首先下载播放mp3的包，比如mp3spi1.9.4.jar。在工程中添加这个包。
播放器演示代码如下
package com.test.audio;
import java.io.File;
import java.awt.BorderLayout;
import java.awt.FileDialog;
import java.awt.Frame;
import java.awt.GridLayout;
import java.awt.Label;
import java.awt.List;
import java.awt.Menu;
import java.awt.MenuBar;
import java.awt.MenuItem;
import java.awt.MenuShortcut;
import java.awt.Panel;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyEvent;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

import javax.sound.sampled.AudioFormat;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.DataLine;
import javax.sound.sampled.SourceDataLine;

public class MusicPlayer extends Frame {
/**
*
*/
private static final long serialVersionUID = -2605658046194599045L;
boolean isStop = true;// 控制播放线程
boolean hasStop = true;// 播放线程状态

String filepath;// 播放文件目录
String filename;// 播放文件名称
AudioInputStream audioInputStream;// 文件流
AudioFormat audioFormat;// 文件格式
SourceDataLine sourceDataLine;// 输出设备

List list;// 文件列表
Label labelfilepath;//播放目录显示标签
Label labelfilename;//播放文件显示标签

public MusicPlayer() {
// 设置窗体属性
setLayout(new BorderLayout());
setTitle("MP3 Music Player");
setSize(350, 370);

// 建立菜单栏
MenuBar menubar = new MenuBar();
Menu menufile = new Menu("File");
MenuItem menuopen = new MenuItem("Open", new MenuShortcut(KeyEvent.VK_O));
menufile.add(menuopen);
menufile.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
open();
}
});
menubar.add(menufile);
setMenuBar(menubar);

// 文件列表
list = new List(10);
list.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
// 双击时处理
if (e.getClickCount() == 2) {
// 播放选中的文件
filename = list.getSelectedItem();
play();
}
}
});
add(list, "Center");

// 信息显示
Panel panel = new Panel(new GridLayout(2, 1));
labelfilepath = new Label("Dir：");
labelfilename = new Label("File：");
panel.add(labelfilepath);
panel.add(labelfilename);
add(panel, "North");

// 注册窗体关闭事件
addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
setVisible(true);
}

// 打开
private void open() {
FileDialog dialog = new FileDialog(this, "Open", 0);
dialog.setVisible(true);
filepath = dialog.getDirectory();
if (filepath != null) {
labelfilepath.setText("Dir：" + filepath);

// 显示文件列表
list.removeAll();
File filedir = new File(filepath);
File[] filelist = filedir.listFiles();
for (File file : filelist) {
String filename = file.getName().toLowerCase();
if (filename.endsWith(".mp3") || filename.endsWith(".wav")) {
list.add(filename);
}
}
}
}

// 播放
private void play() {
try {
isStop = true;// 停止播放线程
// 等待播放线程停止
System.out.print("Start：" + filename);
while (!hasStop) {
System.out.print(".");
try {
Thread.sleep(10);
} catch (Exception e) {
}
}
System.out.println("");
File file = new File(filepath + filename);
labelfilename.setText("Playing：" + filename);

// 取得文件输入流
audioInputStream = AudioSystem.getAudioInputStream(file);
audioFormat = audioInputStream.getFormat();
// 转换mp3文件编码
if (audioFormat.getEncoding() != AudioFormat.Encoding.PCM_SIGNED) {
audioFormat = new AudioFormat(AudioFormat.Encoding.PCM_SIGNED,
audioFormat.getSampleRate(), 16, audioFormat
.getChannels(), audioFormat.getChannels() * 2,
audioFormat.getSampleRate(), false);
audioInputStream = AudioSystem.getAudioInputStream(audioFormat,
audioInputStream);
}

// 打开输出设备
DataLine.Info dataLineInfo = new DataLine.Info(
SourceDataLine.class, audioFormat,
AudioSystem.NOT_SPECIFIED);
sourceDataLine = (SourceDataLine) AudioSystem.getLine(dataLineInfo);
sourceDataLine.open(audioFormat);
sourceDataLine.start();

// 创建独立线程进行播放
isStop = false;
Thread playThread = new Thread(new PlayThread());
playThread.start();
} catch (Exception e) {
e.printStackTrace();
}
}

class PlayThread extends Thread {
byte tempBuffer[] = new byte[320];

public void run() {
try {
int cnt;
hasStop = false;
// 读取数据到缓存数据
while ((cnt = audioInputStream.read(tempBuffer, 0,
tempBuffer.length)) != -1) {
if (isStop)
break;
if (cnt > 0) {
// 写入缓存数据
sourceDataLine.write(tempBuffer, 0, cnt);
}
}
// Block等待临时数据被输出为空
sourceDataLine.drain();
sourceDataLine.close();
hasStop = true;
} catch (Exception e) {
e.printStackTrace();
System.exit(0);
}
}
}

public static void main(String args[]) {
new MusicPlayer();
}
}

Ⅲ 用Java语言编写一个音乐播放器

这个可以用JMF做的，你可以参考下，JMF（Java Media Frame） 看名字你应该可以知道这是干嘛的。 如果需要代码的话邮箱联系我吧：[email protected]

Ⅳ 如何用java做一个音乐播放器

首先下载播放的包，比如mp3spi1.9.4.jar。在工程中添加这个包。

播放器演示代码如下

packagecom.test.audio;
importjava.io.File;
importjava.awt.BorderLayout;
importjava.awt.FileDialog;
importjava.awt.Frame;
importjava.awt.GridLayout;
importjava.awt.Label;
importjava.awt.List;
importjava.awt.Menu;
importjava.awt.MenuBar;
importjava.awt.MenuItem;
importjava.awt.MenuShortcut;
importjava.awt.Panel;
importjava.awt.event.ActionEvent;
importjava.awt.event.ActionListener;
importjava.awt.event.KeyEvent;
importjava.awt.event.MouseAdapter;
importjava.awt.event.MouseEvent;
importjava.awt.event.WindowAdapter;
importjava.awt.event.WindowEvent;

importjavax.sound.sampled.AudioFormat;
importjavax.sound.sampled.AudioInputStream;
importjavax.sound.sampled.AudioSystem;
importjavax.sound.sampled.DataLine;
importjavax.sound.sampled.SourceDataLine;

{
/**

	=-2605658046194599045L;
	booleanisStop=true;//控制播放线程
booleanhasStop=true;//播放线程状态

Stringfilepath;//播放文件目录
Stringfilename;//播放文件名称
;//文件流
AudioFormataudioFormat;//文件格式
SourceDataLinesourceDataLine;//输出设备

Listlist;//文件列表
Labellabelfilepath;//播放目录显示标签
Labellabelfilename;//播放文件显示标签

publicMusicPlayer(){
//设置窗体属性
setLayout(newBorderLayout());
setTitle("MP3MusicPlayer");
setSize(350,370);

//建立菜单栏
MenuBarmenubar=newMenuBar();
Menumenufile=newMenu("File");
MenuItemmenuopen=newMenuItem("Open",newMenuShortcut(KeyEvent.VK_O));
menufile.add(menuopen);
menufile.addActionListener(newActionListener(){
publicvoidactionPerformed(ActionEvente){
open();
}
});
menubar.add(menufile);
setMenuBar(menubar);

//文件列表
list=newList(10);
list.addMouseListener(newMouseAdapter(){
publicvoidmouseClicked(MouseEvente){
//双击时处理
if(e.getClickCount()==2){
//播放选中的文件
filename=list.getSelectedItem();
play();
}
}
});
add(list,"Center");

//信息显示
Panelpanel=newPanel(newGridLayout(2,1));
labelfilepath=newLabel("Dir：");
labelfilename=newLabel("File：");
panel.add(labelfilepath);
panel.add(labelfilename);
add(panel,"North");

//注册窗体关闭事件
addWindowListener(newWindowAdapter(){
publicvoidwindowClosing(WindowEvente){
System.exit(0);
}
});
setVisible(true);
}

//打开
privatevoidopen(){
FileDialogdialog=newFileDialog(this,"Open",0);
dialog.setVisible(true);
filepath=dialog.getDirectory();
if(filepath!=null){
labelfilepath.setText("Dir："+filepath);

//显示文件列表
list.removeAll();
Filefiledir=newFile(filepath);
File[]filelist=filedir.listFiles();
for(Filefile:filelist){
Stringfilename=file.getName().toLowerCase();
if(filename.endsWith(".mp3")||filename.endsWith(".wav")){
list.add(filename);
}
}
}
}

//播放
privatevoidplay(){
try{
isStop=true;//停止播放线程
//等待播放线程停止
System.out.print("Start："+filename);
while(!hasStop){
System.out.print(".");
try{
Thread.sleep(10);
}catch(Exceptione){
}
}
System.out.println("");
Filefile=newFile(filepath+filename);
labelfilename.setText("Playing："+filename);

//取得文件输入流
audioInputStream=AudioSystem.getAudioInputStream(file);
audioFormat=audioInputStream.getFormat();
//转换mp3文件编码
if(audioFormat.getEncoding()!=AudioFormat.Encoding.PCM_SIGNED){
audioFormat=newAudioFormat(AudioFormat.Encoding.PCM_SIGNED,
audioFormat.getSampleRate(),16,audioFormat
.getChannels(),audioFormat.getChannels()*2,
audioFormat.getSampleRate(),false);
audioInputStream=AudioSystem.getAudioInputStream(audioFormat,
audioInputStream);
}

//打开输出设备
DataLine.InfodataLineInfo=newDataLine.Info(
SourceDataLine.class,audioFormat,
AudioSystem.NOT_SPECIFIED);
sourceDataLine=(SourceDataLine)AudioSystem.getLine(dataLineInfo);
sourceDataLine.open(audioFormat);
sourceDataLine.start();

//创建独立线程进行播放
isStop=false;
ThreadplayThread=newThread(newPlayThread());
playThread.start();
}catch(Exceptione){
e.printStackTrace();
}
}

classPlayThreadextendsThread{
bytetempBuffer[]=newbyte[320];

publicvoidrun(){
try{
intcnt;
hasStop=false;
//读取数据到缓存数据
while((cnt=audioInputStream.read(tempBuffer,0,
tempBuffer.length))!=-1){
if(isStop)
break;
if(cnt>0){
//写入缓存数据
sourceDataLine.write(tempBuffer,0,cnt);
}
}
//Block等待临时数据被输出为空
sourceDataLine.drain();
sourceDataLine.close();
hasStop=true;
}catch(Exceptione){
e.printStackTrace();
System.exit(0);
}
}
}

publicstaticvoidmain(Stringargs[]){
newMusicPlayer();
}
}

Ⅳ 如何用Java来编写一个音乐播放器

首先要在环境电脑中安装下JMF环境，才能引入javax.sound.sampled.*这个包，一下是用过的代码
package TheMusic;
import java.io.*;

import javax.sound.sampled.*;

public class Music {

public static void main(String[] args) {

// TODO Auto-generated method stub

//修改你的音乐文件路径就OK了

AePlayWave apw=new AePlayWave("突然好想你.wav");

apw.start();

}

}

在程序中实例化这个类，启动线程，实例化的时候参照Test修改路径就OK播放声音的类
Java代码

public class AePlayWave extends Thread {

private String filename;

public AePlayWave(String wavfile) {

filename = wavfile;

}

public void run() {

File soundFile = new File(filename);

AudioInputStream audioInputStream = null;

try {

audioInputStream = AudioSystem.getAudioInputStream(soundFile);

} catch (Exception e1) {

e1.printStackTrace();

return;

}

AudioFormat format = audioInputStream.getFormat();

SourceDataLine auline = null;

DataLine.Info info = new DataLine.Info(SourceDataLine.class, format);

try {

auline = (SourceDataLine) AudioSystem.getLine(info);

auline.open(format);

} catch (Exception e) {

e.printStackTrace();

return;

}

auline.start();

int nBytesRead = 0;

byte[] abData = new byte[512];

try {

while (nBytesRead != -1) {

nBytesRead = audioInputStream.read(abData, 0, abData.length);

if (nBytesRead >= 0)

auline.write(abData, 0, nBytesRead);

}

} catch (IOException e) {

e.printStackTrace();

return;

} finally {

auline.drain();

auline.close();

}

}

}

Ⅵ 求音乐播放器java源代码

import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import java.net.*;

import javax.swing.*;
import java.io.File;

class AudioPlayDemo extends JFrame implements ActionListener {
boolean looping = false;
File file1 = new File("music\\明天会更好.wav");
AudioClip sound1;
AudioClip chosenClip;

JButton playButton = new JButton("播放");
JButton loopButton = new JButton("循环播放");
JButton stopButton = new JButton("停止");
JLabel status = new JLabel("选择播放文件");
JPanel controlPanel = new JPanel();
Container container = getContentPane();

public AudioPlayDemo() {
try {
sound1 = Applet.newAudioClip(file1.toURL());
chosenClip = sound1;
} catch(OutOfMemoryError e){
System.out.println("内存溢出");
e.printStackTrace();
} catch(Exception e){
e.printStackTrace();
}
playButton.addActionListener(this);
loopButton.addActionListener(this);
stopButton.addActionListener(this);
stopButton.setEnabled(false);

controlPanel.add(playButton);
controlPanel.add(loopButton);
controlPanel.add(stopButton);

container.add(controlPanel, BorderLayout.CENTER);
container.add(status, BorderLayout.SOUTH);

setSize(300, 130);
setVisible(true);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //关闭窗口时退出程序
}

public void actionPerformed(ActionEvent event) {
if (chosenClip == null) {
status.setText("声音未载入");
return;
}
Object source = event.getSource(); //获取用户洗涤激活的按钮

if (source == playButton) {
stopButton.setEnabled(true);
loopButton.setEnabled(true);
chosenClip.play();
status.setText("正在播放");
}

if (source == loopButton) {
looping = true;
chosenClip.loop();
loopButton.setEnabled(false);
stopButton.setEnabled(true);
status.setText("正在循环播放");
}
if (source == stopButton) {
if (looping) {
looping = false;
chosenClip.stop();
loopButton.setEnabled(true);
} else {
chosenClip.stop();
}
stopButton.setEnabled(false);
status.setText("停止播放");
}
}
public static void main(String s[]) {
new AudioPlayDemo();
}
}
这功能不齐，不能下载，也不能播放mp3格式音乐，是用来播放wav格式音乐的，（但你可以在千千静听里把mp3格式转换为wav格式）
