In this chapter, you learned about the basics of making a simple generic class, so that one class can operate on many different data types. A great benefit of generics is flexibility. You created a simple generics class that worked with different data types, made generic parameters, initialized a collection of integers to their array and displayed the results, and then changed the data types in the generics class to doubles and decimals.
In the next chapter, you will learn about generic methods, or methods that can operate on different data types. You will also learn about constraining a method in terms of the data types that it can operate on, so we'll add a concept called constraints.
