Answer 1

Assuming that the url will end with .XXX (continuous extension)

String[] splitted = url.split("\\.");
return (splitted[splitted.length-1]); //will return the last string after the last "."

Where url is your url (www.google.com in this case).

Note that if the url is http://www.google.com/ then the code will return .com/. So you need to perform a check if the result contains / character. (Hint: look for contains in the String API).
