I'm just trying this out, still novice in Java. I'm putting this in an Android project. I initially tried importing this as a project and I didn't immediately get it to work, so I just opted to import the library .jars and the source java.
I put the google collections jar in my /libs folder (I also tried with the latest guava, and I'm going to go with that ultimately if I can; same error here). I put Maybe.java in my /src directory.
So I get one error I don't understand: Type mismatch: cannot convert from Maybe<captrure#2-of ? extends U> to Maybe<U>
This is for the function: public <U> Maybe<U> to(Function<? super T, ? extends U> mapping).
For now I can just comment out that function, from your tutorial it sounded like it wasn't critical. But it seems cool so it'd be nice to have.
