[Star Wars] Is the Death Star big enough to generate its own gravity?

The original death Star is 160 km in diameter. Approximately the size of a "small moon" are moon has enough mass to generate a little bit of gravity. I'm thinking that the death Star is large enough to generate some of it's own gravity but skeptical about whether or not it's large enough to have the gravity that is depicted in the films. If it's large enough to generate some gravity how do they supplement it?

Everything that has mass has gravity, so yes the Death Star is big enough to have it.  It's not as dense as a moon meaning its natural gravity would be weaker than a moon of equivalent size.  

It's pretty evident that they've figured out how to simulate gravity on space borne craft however. It's likely the same technology that allows people to mill about the Falcon without floating works on the people who live and work on the Death Star.
