Answer 1

Method get requires the protocol as part of the URL.
Change:
String baseurl = "www.google.com";
To:
String baseurl = "http://www.google.com";

Answer 2

Please check your calling method to open the browser. I believe you have written code like this:
driver.get("Url"); //Incorrect Code
Correct should be like:
driver.get(Url);// Correct Code
