java - Google Calendar API - How To Create Service -

looking @ google calendar api v3 documentation, see them show under events.list snippet of code.

string pagetoken = null; {   events = service.events().list('primary').setpagetoken(pagetoken).execute();   list<event> items = events.getitems();   (event event : items) {     system.out.println(event.getsummary());   }   pagetoken = events.getnextpagetoken(); } while (pagetoken != null); 

i wondering how person go setting "service" in line

events = service.events().list('primary').setpagetoken(pagetoken).execute(); 

i think might

calendar service = calendar(httptransport, jsonfactory, httprequestinitializer)  

but not 100% sure asking help. thanks!

this seems code web based calendar thing, might need web services run on android.
