Prerequisites: Introduction to Recursion
Purpose of tutorial:
This video is part of a series of tutorials that serve as an introduction to programming topics.
The video introduces the concept of generics in Java. It presents the motivation for this mechanism, that is, why generic or parameterized classes would be used.
In this video, we present syntax for
* declaring a generic class
* declaring methods in a generic class
* using a type parameter as a placeholder for an actual class type
As part of the discussion of generics, we introduce the concept of wrapper classes for the Java primitive types.
