What's in a Type? A Mathematical View of the Java Type System
Sunday - Oct 19 9:00 AM PDT - Salon 2
Over the years, Java developers have learned through trial-and-error the best ways to use Java's type system. But certain parts of the type system like wildcard generics and covariant return types are
under used; in-part, because they are not well understood.
Fortunately by going back to the mathematical roots of type systems, we can understand not only wildcard types and covariance, but also why we should prefer composition over inheritance and even how compilers perform some of their optimization magic.
