What are the differences between specific and general deterrence?

Specific Deterrence is making an attempt to deter one person from repeating an act.

General Deterrence is making an attempt to deter society from engaging in an act.

If Joe stole from a store, specific deterrence would be to punish Joe to the point where he wouldn't repeat the act. General deterrence would be to make an example out of Joe, so other people do not steal.
