empNum is an explicit parameter as it is passed as an argument to the method. It is not an implicit parameter that is automatically passed by the system. An implicit parameter is usually the object on which the method is invoked if it is an instance method. empNum is also not the object on which this method is invoked since there is no reference to the keyword "this". It is also not an instance variable since it is not declared at the class level but passed as a parameter to the method.
