Lecture
This lecture covers exceptions in Scala, defining exception classes, handling exceptions with try/catch expressions, and the shortcomings of exceptions. It introduces the scala.util.Try type as an alternative to try/catch, explaining its structure, creation, composition, and the definition of flatMap and map on Try. The lecture concludes with a discussion on whether Try is a monad, highlighting the failure of the left unit law and the 'bullet-proof' principle.
