Help with Twitter 4j and general geolocation of user in an area

Hi,
I found this sketch on this forum posted by mrslash and it contains a code that is exactly what I am looking for. I am completely new to processing and I am not sure how to troubleshoot this problem. I am looking to filter tweets by a specific location and then have the data for the number of tweets in a given time period saved as a csv file. When I run this sketch I receive the error "cannot find a class or type named "date". I have my Oauth and the twitter4j library installed. Can anyone try to run this sketch and let me know if they get the same problem or let me know what I need to do to fix this issue?

Any help is appreciated.

I didn't try your sketch but to deal with date() you would need to import java.util.Date;
