It signals to the compiler that your method is in fact a generic method. Otherwise T would not be recognised as a type, but a class name. If you wrote this for example:then the compiler expects that T is a class type for the parameter, not a generic type to be substituted. You'll probably get compiler errors about the class not being found (unless you happen to have a class called T lying around!).
