 jungler but I dont think that is wise with Olaf.
Masteries
Masteries depend again on jungle/lane
The Jungle masteries that I use might look a little odd but it works
11/9/10
Crit (3) and Smite (1), Attack speed (4), Armor Pen (3)/ Magic Resist (1) and Armor (3), Dodge (4), Nimbleness (1)/Perseverance (3) and Ghost (1), Xp Gain (4), Monster Buff Duration (2). If you aren't level 30 and you only have some masteries to pick from i would prioritize the utility tree then the offense tree then the defense tree but really you want to have most of the listed maseteries and runes if you are going to jungle because they make a big difference.
The laning Masteries can be 21/9/0 or 11/29/0 or 21/0/9
21 in Offense is standard crit, attack speed, armor pen, bonus damage, crit damage, total damage in any case. For the 11/29 build you get to armor penetration at least.
The 29 to pick up in the Defense tree are armor and magic resist, dodge if you have dodge runes, nimbleness (if you have dodge) and flat damage reduction and health. Feel tree to pick up the extra attack speed bonus but the additional ability power it grants wont do you much good.
In the Utility tree you want to pick up Ghost and Regeneration, Experience Gain, and then gold or meditation or monster buff. For the good it does I would pick up 1 in Meditation as the monster buff duration would be going to your jungler or your AP carry and 1 gold in 10 isnt all that useful on Olaf. It is better to find youself not mana starved.

Really long answer for what looks like a short question but I hope it helps.
I also encourage you to read guides for Olaf (or any champion you are starting to learn) to get a sense for what others recommend. Then play them out see what you like and make your own build. If you are going to jungle I suggest even more strongly to check out a guide specifically for that as the starting items and route through the jungle can be fairly specifically worked out to maximize profit.
