Usage

From source file:Main.java

public static void main(String[] args) throws Exception {

    URL google = new URL("http://www.google.com/");

    while ((tmp = dis.readLine()) != null) {
        inputLine.append(tmp);
        System.out.println(tmp);
    }
    // use inputLine.toString(); here it would have whole source
    dis.close();
}
