Guava’s Strings.isEmptyOrNull (String) method makes it easy to build simple and highly readable conditional statements that check a String for null or emptiness before acting upon said String.

String, object, and struct are reference type examples. The null keyword is a literal that represents a null reference with the C# .NET environment.

For UTF-8 character encoding, C# 11 enables conversion of string literals containing only UTF-8 characters to their byte representation. UTF-8 is used in many scenarios, particularly on the web.
