how to get the second ferivatives of a group of data

Re: [all] Generics and Return Type?

Hi James and Matt, and thank you for answering. James' code is nice, and it is exactly what I was talking about. Anyway, it covers one of the possible needs : the return type of a method; while also parameters can be parametrized and in some situations (like a List) simply knowing which type the p
