title: How to get HTML links from a URL
body: <p>I'm just starting out on my Networking Assignment and I'm already stuck. 
  Assignment asks me to check the user provided website for links and to determine if they are active or inactive by reading the header info. 
  So far after googling, I just have this code which retrieves the website. I don't get how to go over this information and look for HTML links. 
  Here's the code: </p>
  
  <pre><code>import java.net.*; 
  import java.io.*; 
  
  public class url_checker { 
      public static void main(String[] args) throws Exception { 
          URL yahoo = new URL("http://yahoo.com"); 
          URLConnection yc = yahoo.openConnection(); 
          BufferedReader in = new BufferedReader( 
                                  new InputStreamReader( 
                                  yc.getInputStream())); 
          String inputLine; 
          int count = 0; 
          while ((inputLine = in.readLine()) != null) { 
              System.out.println (inputLine);                
              }      
          in.close(); 
      } 
  } 
  </code></pre>
  
  <p>Please help.
  Thanks!</p>
