Following would be the input to the code:
website, Keyword, Crawl interval
The crawler,based on the Crawl interval, should automatically perform a google search for the Keyword targeting the Website given for that particular Keyword. In the google search results, you can notice that, google provides information as to when that url within the website was updated(eg; 45 minutes ago, 3 hours ago, 2 days ago, Aug 22, 2013 and so on). If in search result, you get a result(url or urls) which came after the last crawled time(say n minutes ago, n days ago etc.), then those url's need to be fetched to an arraylist.
Any help or suggestion, implementing the mechanism above using java is much appreciated.
Correct solutions or guidance, preferably with code snippets will be awarded full points.
