Since a value in quotes is really a String object, you can call methods like .equals() on it, as follows:
if (userName != null && userName.equals("Fred")) ... // could be written as follows: if ("Fred".equals(userName)) ...
If you cram too much cleverness into one line the code will quickly become unreadable, as in the following real world example:
dlLocal = !"false".equals(processing.getConfig().getProperty(DOWNLOAD_LOCAL_SETTING));
