package javax.media does not exist
提问by Masu
I am working on an audio player and need to add pause()and play()features in it to connect with JButtons. The problem is I am not able to import Media package as it says package does not exist. I cannot find anywhere it online to download the package. Same goes for AudioPlayerclass which gives bad class file error.

Based on your question,
根据你的问题，
You can down load java.media
你可以下载java.media
then use
然后使用
import javax.media.*;
then you can declare like
然后你可以声明像
Player audioplayer = Manager.createRealizedPlayer(file.toURI().toURL());
And
和
audioplayer.start();and audioplayer.stop();
audioplayer.start();和 audioplayer.stop();
Here filemeans where the source file saved.
这里file表示源文件的保存位置。
NB: you can use JMF jar file
注意：您可以使用 JMF jar 文件
Try like this
像这样尝试
try {
audioplayer = Manager.createRealizedPlayer(file.toURI().toURL());
} catch (IOException ex) {
Logger.getLogger(MY_MP3_PLAYER.class.getName()).log(Level.SEVERE, null, ex);
} catch (NoPlayerException ex) {
Logger.getLogger(MY_MP3_PLAYER.class.getName()).log(Level.SEVERE, null, ex);
} catch (CannotRealizeException ex) {
Logger.getLogger(MY_MP3_PLAYER.class.getName()).log(Level.SEVERE, null, ex);
}
OR Try the sample code given below
或尝试下面给出的示例代码
import java.io.File;
import java.io.IOException;
import java.util.Scanner;
import javax.media.CannotRealizeException;
import javax.media.Manager;
import javax.media.NoPlayerException;
import javax.media.Player;
public class Mp3Player {
public static void main(String[] args) throws IOException, NoPlayerException, CannotRealizeException {
// Source of song file
File f=new File("your path in which mp3 file is saved");
// Create a Player object that realizes the audio
final Player p=Manager.createRealizedPlayer(f.toURI().toURL());
// Start the music
p.start();
// Create a Scanner object for taking input from cmd
Scanner s=new Scanner(System.in);
// Read a line and store it in st
String st=s.nextLine();
// If user types 's', stop the audio
if(st.equals("s"))
{
p.stop();
}
}
}

It is a late answer, but you can use the Maven dependency:
这是一个迟到的答案，但您可以使用 Maven 依赖项：
<!-- https://mvnrepository.com/artifact/javax.media/jmf -->
<dependency>
<groupId>javax.media</groupId>
<artifactId>jmf</artifactId>
<version>2.1.1e</version>
</dependency>
