Team's Response

The add module feature is to add modules. Hence, the message should be clear and simple for the user.

If the module already exist, the message telling the user that the module already exist is clear and concise. The message that "CS2113 already exist" is clear to the user that CS2113 already exist in the list of modules.

The user can simply type the list command to view the existing modules.

If the list of modules is shown when the user wants to add a module, it will be confusing and inconvenient for the user as the list of modules should be shown when the user types the list command instead.
