    Default Stock price of a symbol

    I m trying to get the current stock price of a symbol using socket but the program is getting terminated.
    String yahoo = "finance.yahoo.com" ;
    final int httpd = 80;
    Socket sock = new Socket(yahoo, httpd);

    BufferedWriter out = new BufferedWriter( new OutputStreamWriter(sock.getOutputStream() ) );

    String cmd = "GET/d/q?s= " +symbol[j] +"\n";
    out.write(cmd);
    out.flush();

    BufferedReader in =new BufferedReader(new InputStreamReader( sock.getInputStream() ) );
    String s=null;

    please help me out ..

    --- Update ---

    import java.io.*;
    import java.net.*;
    public class stockquotes {

    public static void main(String a[]) throws IOException {
    String[] symbol={"ibm"};
    for (int j = 0; j<symbol.length ; j++)
    try{

    String yahoo = "finance.yahoo.com" ;
    final int httpd = 80;
    Socket sock = new Socket(yahoo, httpd);

    BufferedWriter out = new BufferedWriter( new OutputStreamWriter(sock.getOutputStream() ) );

    String cmd = "GET/d/q?s= " +symbol[j] +"\n";
    out.write(cmd);
    out.flush();

    BufferedReader in =new BufferedReader(new InputStreamReader( sock.getInputStream() ) );
    String s=null;
    int i, k;
    // pick out the stock price from the pile of HTML
    // it's in bold, so get the number following "<b>"
    while ( (s=in.readLine()) != null) {
    if (s.length()<25) continue;
    if ((i=s.indexOf(symbol[j].toUpperCase())) < 0) continue;
    s=s.substring(i);
    if ((i=s.indexOf("<b>")) < 0) continue;
    k = s.indexOf("</b>");
    s=s.substring(i+7,k);
    System.out.println(symbol[j] +" is at "+s);


    }
    }catch (IOException ioex) {
    ioex.printStackTrace();
    }
    }
    }
