Some people use UV filters as lens protectors. Highly debated, 'kiasu' people get one for each lens. Since it's a piece of extra glass in front of the lens it can also have negative side effects on image under certain conditions. Search for 'lens flare' and 'ghosting'.

im curious on what your friend told you about it..
unless its polarize or ND filters you talking here.
Understand first the purpose, then the decision becomes easier.
Yes, you can still put a lens cap on any normal filter. But there are slim versions of some filters. There you can't put on your normal lens cap. But those filters come with a special lens cap then.
