Because it is a Enum. For java Enums, you need to first define its values, followed by a semicolon, then the methods. In this case, there's no values because we are only using Enum to keep ClientUtils singleton, but you still need the semicolon before defining methods. You could see that removing that semicolon will cause compiling errors.
