Lesson Review

This lesson was all about generics and collections:

• Generics are a way to parameterize class types into classes, methods and variables so that we eliminate the need for casting, have stronger type checks at compile time, and develop generic algorithms.
• Collections are data structures that were created to provide improved interoperability and performance. Collections provides a more effective framework and architecture for storing, retrieving, and processing data.

In the next lesson, we'll look at some additional, advanced collection types.
