Log into twitter?

Programmer Question

Ok, basically what I am trying to do is get a boolean if I have logged in or not. I am using the Twitter4j library and they gave me the following three things to look at.

https://github.com/yusuke/sign-in-with-twitter/blob/master/src/main/java/twitter4j/examples/signin/CallbackServlet.java

I have no idea how to log in and get if I logged in successfully.

Thanks, and I have no code btw... all I did was basically copy code and try different things.

PS. On a separate note how do I learn how to use someone elses library?
