Passing links from a file (java)

SoupyNorman

Hi,

In a bit of a pickle at the moment, I'm doing a project which requires me to

• Input a web link
• download it's contents to file
• parse the content for all sites the site links to
• check each link individually to see if they are dead or alive, if dead return the response code

I have 1-3 done however one of the they are separate classes and I cant figure out how to get each link to pass to my checker class one by one.

Obviously I am not looking for a straight answer (I know how it works here!) but a nudge in the right direction would be great.

The 1st class downloads the links to a .txt file and they are displayed line by line like so:


http://boards.ie/vbulletin/newthread.php?do=newthread&f=25
https://mail.google.com/mail/
http://www.daft.ie/


In another class I can check one link for the response code....

if(
res.getResponseCode() == HttpURLConnection.HTTP_OK)
System.out.println("Connection is good Roger");
else
System.out.println("There were two Crabs, they work in pairs \n and the response code is \t"+res.getResponseCode());

Thanks.

Rather than putting the links out to a text file, why don't you define a method on your checking class that accepts a URL, then performs the check and passes back a success or failure message?

something like

public String checkLink(URL url) {

}

which you call in your controlling class.
