Sun.Audio.*;

I want to use the sun.audio.* classes in my applet.
However, I do not want to use: import sun.audio.*;, because not all browsers have the sun.audio.*-classes. Rather I want to use:

try {
  audioStream = Class.forName(sun.audio.AudioStream);
  audioPlayer = Class.forName(sun.audio.AudioPlayer);
}
catch {}

However, when I do this, I can obviously not declare a public variable: public AudioPlayer audioPlayer;, because the package has not yet been imported.

Any suggestions for how to deal with this?

Create an interface with the needed methods, impement it in a class
which does these audio things like this:

public interface AudioInterface
{
  public void play();
}

public class AudioFacade implements AudioInterface
{
  AudioStream stream;
  AudioPlayer player;
  public AudioFacade()
  {
   stream = new AudioStrem( ... );
   player = new AudioPlayer( ... );
  }
  public void play()
  {
    player.play();
  }
}

and use it like this:

AudioInterface audio = null;
try {
  audio = class.forName( "AudioFacade").newInstance();
} catch( Throwable t ) {
  // could not create...
}
if( audio != null )
{
  audio.play();
}

This way you have no direct reference to the AudioFacade and your applet
doesn't need those classes for beeing loaded.
