I got this code from one of my friend.

import java.io.*;
import javax.sound.sampled.*;
public class xx
{
    public static void main(String args[])
    {
        try
        {
            File f=new File("mm.wav");
            AudioInputStream a=AudioSystem.getAudioInputStream(f);
            AudioFormat au=a.getFormat();
            DataLine.Info di=new DataLine.Info(Clip.class,au);
            Clip c=(Clip)AudioSystem.getLine(di);
            c.open(a);
            c.start();
        }
        catch(Exception e)
        {
            System.out.println("Exception caught ");
        }
    }
}

But i didn't understand what this line means Cilp c=(Clip)AudioSystem.getLine(di); what (clip) represents....? And my 2nd problem is what is the DataLine is it an interface and what is the meaning of this statement DataLine.Info....?
