viewRequest method is used in order to view the topic requests for both the normal and administrator users. It
takes two parameters:

• user ID: Represents the user ID that requests to view the topic requests.

• status: Represents the status of the topic requests that will be retrieved. It can be one of

three values (1 for pending, 2 for rejected, and 3 for approved; these values are coded in the
Constants interface that is shown in Listing 13-14).
