What kind of Database use as local database for PC Software?

I want to build simple a Windows PC Software with Java. I need to store some extra data like 100 phone contacts. I can do with Oracle or MySQL database or Array in code. But the problem is this DBMS need server offline or online and I don't want to put data direct on code.If I use from my localhost When I will give it to my friends the can't access it. I also don't want to i use online database. I just want local database or resource system like android values resource or sqlite. How can I do it? Any ideas are welcomed.
