Normally you can so long as the caller is presenting their number through Calling Line Identification (CLI) - ie you can see the incoming number on the screen.
If you can see the number, save the number into your phonebook. Create a Group in your phonebook and put the number in it. Then normally you can automatically reject calls from a Group - either by the Group options, or by the settings under the phones Profiles.

You can't prevent anyone from calling or sending texts to your number, but you can easily set your Nokia 1112 to ignore the calls as follows:

Menu -> Settings -> Call Settings -> No. Screening -> Options -> Add

You can also retrieve the number to screen:

Menu -> Call Register -> Received Calls -> Options -> Add to scrn. list.

Calls from screened numbers will not ring on your phone, you will see the number on your screen with a dustbin symbol; messages from screened numbers will go silently to the screened messages folder.

I hope this helps.
