Description
Java’s powerful generics has been available to developers for ten years now and is extensively used throughout both core and third party libraries. Unfortunately, it's not as well understood as it could be. This course is here to help. We’ll both shine a light on the common use cases of generics on classes, methods, or interfaces and also peer into some of the darker corners such as type bounds and wildcards.
