How to get audio device information connected with MAC system?

Question

I want to know the samplerate (the number of samples per second) supported by the device connected with the MAC system.
I am also pasting the code as below where I need that info.
// Using PCM 44.1 kHz, 16 bit signed,stereo.
          AudioFormat audioFormat = new AudioFormat(AudioFormat.Encoding.PCM_SIGNED,  //     the audio encoding technique
          44100.0F,// sampleRate           the number of samples per second
          16,      // sampleSizeInBits the number of bits in each sample
          2,       // channels           the number of channels (1 for mono, 2 for stereo, and so on)
          4,       // frameSize           the number of bytes in each frame
          44100.0F,// frameRate          the number of frames per second
          false);  // bigEndian          indicates whether the data for a single sample is stored in big-endian byte order (<code>false</code> means little-endian)

Can you sugget something in that area.That's not an issue that's specific to MAC, it'd be specific to any system with a limited number of supported capture formats.
I've handled this problem in the past by generating an array full of all of the AudioFormat objects I'd consider acceptable, and I just iterate through them until I can find a TargetDataline that supports it.
TargetDataLine tdl = null;
/* Write your own code to get an array of acceptable formats here */
AudioFormat formats[] = JavaSoundFormats.getFormatList();
for (AudioFormat format : formats) {
    DataLine.Info dlinfo = new DataLine.Info(TargetDataLine.class,
                                             format);
        if (AudioSystem.isLineSupported(dlinfo)) {
            try {
                audio_in_format = format;
                tdl = (TargetDataLine)AudioSystem.getLine(dlinfo);
                break;
            catch(LineUnavailableException e) {
                // No need to do anything
/* If we don't have a targetdataoutput object, give up */
if (tdl == null) {
    System.err.println("No TargetDataLines found!");
    System.exit(1);
}
