If you work with domains you could use Google Guava InternetDoMainNames class. It is very simple

InternetDomainName.from("www.xyzw.com").publicSuffix();

How to use: https://code.google.com/p/guava-libraries/wiki/InternetDomainNameExplained http://koziolekweb.pl/2014/03/30/pomocna-guava-informacje-o-domenie/ (with example - translation to english is posible)

You can do:

String r = strArray[strArray.length - 1];

Or:

String r = domain.substring(domain.lastIndexOf(".") + 1);

 String domain = "www.xyzw.com";
 String[] strArray = domain.split("\\.");
  System.out.println(strArray[2]);

String s = domain.substring(domain.lastIndexOf(".")+1);

Consider inserting error checks for the case that the string does not contain .
