How can I play an MP3 file? [duplicate]

问题

I am trying to access an MP3 audio file saved in my source folder, so that I can play it in a Java program (application, not applet).

The problem I seem to be having is that I cannot import javax.media. I have been trying to install the Java media framework, but it gives me an error report:

"unable to execute...".

I use JDK v7 u45 and had tried it on JDK v7 u40, but I can't seem to figure out what to do. I tried calling

import javax.media.*;

and it returns a syntax error on the "media", claiming import is not available. Does jmf not work in Java 7?

Try the following way. It's working and also import the following classes.

import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;

try{
    AudioInputStream audioInputStream =
        AudioSystem.getAudioInputStream(
            this.getClass().getResource("<Path of relative sound file in src folder>"));
    Clip clip = AudioSystem.getClip();
    clip.open(audioInputStream);
    clip.start();
}
catch(Exception ex)
{
}

Your problem is likely that javax.media is not in your library. Make sure that you include the correct JAR file in your libraries (See Eclipse missing imports).

I previously did a bunch of searching to attempt to find out how to play audio in Java. What I found is that JavaFX is the easiest to use for playing MP3 files. For playing other inputs, I created a SourceDataLine (under the direction of this tutorial) and used that.

The file MP3.java is a bare bones Java program that uses JLayer to play the MP3 file specified on the command line. It plays the MP3 file in a separate thread, so you are free to perform other computation while the song plays. In order to compile and execute it, you need to put the file jl1.0.jar in your current working directory (or classpath). Instructions for compiling and executing (depending on your operating system) are included in the .java file.

For another method that I think is fairly simple and the most up-to-date method in playing MP3 files, use the JavaFX library. A very easy way to use JavaFX is to install the e(fx)clipse plugin. On that website, go to "install" at the top and follow the instruction on how to install the plugin into Eclipse. In Eclipse (after the plugin is installed), go to File -> New -> Other... -> JavaFX Project, and then your JavaFX imports will work.

The answer to the question Playing audio using JavaFX MediaPlayer in a normal Java application? (which was already linked to in another answer) was very helpful to me, and may also be helpful to you.
