Java Jeopardy Game Help with Sound

[AshleyI]

Hi,

Can someone kindly help me and show me how I can play an audio clip at the beginning of my game. I already have the audio clip and it's a URL. I only have basic knowledge in Java. I tried searching and this is what I found so far:

code:

try {         // From file         AudioInputStream stream = AudioSystem.getAudioInputStream(new File("audiofile"));             // From URL         stream = AudioSystem.getAudioInputStream(new URL("http://hostname/audiofile"));             // At present, ALAW and ULAW encodings must be converted         // to PCM_SIGNED before it can be played         AudioFormat format = stream.getFormat();         if (format.getEncoding() != AudioFormat.Encoding.PCM_SIGNED) {             format = new AudioFormat(                     AudioFormat.Encoding.PCM_SIGNED,                     format.getSampleRate(),                     format.getSampleSizeInBits()*2,                     format.getChannels(),                     format.getFrameSize()*2,                     format.getFrameRate(),                     true);        // big endian             stream = AudioSystem.getAudioInputStream(format, stream);         }             // Create the clip         DataLine.Info info = new DataLine.Info(             Clip.class, stream.getFormat(), ((int)stream.getFrameLength()*format.getFrameSize()));         Clip clip = (Clip) AudioSystem.getLine(info);             // This method does not return until the audio file is completely loaded         clip.open(stream);             // Start playing         clip.start();     } catch (MalformedURLException e) {     } catch (IOException e) {     } catch (LineUnavailableException e) {     } catch (UnsupportedAudioFileException e) {     }

I pasted this code in a seperate method; and changed the URL link and I get 24 errors ... that a lot of these variables are not defined such as stream, AudioFormat etc.. Should I be declaring something in class or importing?? Please help and oh I m using Visual Age for Java 2.0.

P.S. Yes, This topic had been posted before and there is the same link given to the code.. but no explanation. And I absolutely have no idea what to do next..

Thanks,
Ashley.

All variables must be declared, or else they cannot be used. As for AudioFormat, it's a class, and that you must import from the javax.sound.sampled package. Unfortunately, I don't understand too much about the javax.sound.sampled package, but I do remember that it was really confusing and complicated, and I ended up using the Applet class's AudioClip interface for my own project.

If your program is an applet, you can use your applet's built-in method getAudioClip (url), or use Applet's static method, Applet.newAudioClip (url), to create a new AudioClip object, and you don't have to worry about formats or anything else like that.

Unfortunately, my game is created in consoles. And I tried to import javax.sound.sampled.*; and I am getting an error: Import refers to a missing package. Does anyone know anything about that? And how do I declare other variables? The Q may sound stupid, but I have no idea what I m doing anymore.

Hmmmm, that certainly is a problem. I don't know much about consoles, mainly cuz I don't use them, but I do know the RTP's console uses its own separate library, and you'd have to find the directory where the library is located, and add in the packages in manually. I would recommend, however, that you use the Applet package. I'm pretty sure your console should have it.

You declare variables in a line by first stating the type of object they'll be referring to, and the name of the variable:

Java:

AudioInputStream stream

AudioInputStream would be the type of object that the variable is referring to, and stream is the name of the variable.
