    /**
     * Creates a stream socket and connects it to the specified port
     * number on the named host.
     * <p>
     * If the specified host is <tt>null</tt> it is the equivalent of
     * specifying the address as <tt>{@link java.net.InetAddress#getByName InetAddress.getByName}(null)</tt>.
     * In other words, it is equivalent to specifying an address of the 
     * loopback interface. </p>
     * <p>
     * If the application has specified a server socket factory, that
     * factory's <code>createSocketImpl</code> method is called to create
     * the actual socket implementation. Otherwise a "plain" socket is created.
     * <p>
     * If there is a security manager, its
     * <code>checkConnect</code> method is called
     * with the host address and <code>port</code> 
     * as its arguments. This could result in a SecurityException.
     *
     * @param      host   the host name, or <code>null</code> for the loopback address.
     * @param      port   the port number.
     *
     * @exception  UnknownHostException if the IP address of 
     * the host could not be determined.
     *
     * @exception  IOException  if an I/O error occurs when creating the socket.
     * @exception  SecurityException  if a security manager exists and its  
     *             <code>checkConnect</code> method doesn't allow the operation.
     * @see        java.net.Socket#setSocketImplFactory(java.net.SocketImplFactory)
     * @see        java.net.SocketImpl
     * @see        java.net.SocketImplFactory#createSocketImpl()
     * @see        SecurityManager#checkConnect
     */
    public Socket(String host, int port)
	throws UnknownHostException, IOException

Unpack the sources, google for sample code ( not all of which will be good code )
