When designing a class, you want it to be able to handle different types of data
Then you need to use the type as a parameter.
For example<T>, List, the designer allows it to store multiple types of objects, represented by a T,
It is up to the user to decide what T is when it is used.
Generic class. Like what:
List class<T>, you can define it yourself:
These classes all support List methods, including: Add, Remove, Clear.

Angle brackets are also used in commissions
Action<int,string> indicates a delegate with an incoming parameter int and no return value for string
