Introducing generics

All of our code so far has been very specific in terms of defining and using types. However, there will be cases where you need a class or method to treat its entities in the same way, regardless of its type, while still being type-safe. Generic programming allows us to create reusable classes, methods, and variables using a placeholder, rather than a concrete type.

When a generic class instance is created at compile time or a method is used, a concrete type will be assigned, but the code itself treats it as a generic type. Being able to write generic code is a huge benefit when you need to work with different object types in the same way, for example, custom collection types that need to be able to perform the same operations on elements regardless of type, or classes that need the same underlying functionality.
