Note that the class StringUtils is not a class from the standard Java API. It's probably a class from some library, or even defined in your own software.

Most likely it checks if the string that you pass in is null or "". It's just a convenience method, so that you don't have to write code like this all the time:

Empty may or may not also mean that a String only contains whitespace. If you're talking about Apache Commons Lang then they have a separate method for that, StringUtils.isBlank.
