Hello, fellow coder! Today, we'll dive into Kotlin's Abstraction principle, a powerful tool in Object-Oriented Programming. Abstraction is our superhero against seemingly overwhelming complexity, revealing only the necessary details. Are you ready for the fun?

Imagine abstraction as a superboat, stripping off the complexities and giving you just the essentials to operate effectively. It’s not about understanding all the intricate details; it is about focusing on what truly matters. Think of it this way — to drive a car, you only engage with its external controls while the complex workings beneath remain hidden.

In Kotlin, objects are defined through classes. Every class serves as a preliminary blueprint for an object. It stipulates both the data (properties) and their potential behaviors (functions). Similar to a car’s control panel, an object's class provides a user-friendly interface, concealing the complex mechanics within.

When utilizing a Kotlin List, you employ functions like add(), remove(), and sort() through the appropriate collections. You do so without needing to comprehend how Kotlin manages the list's memory space. The internal workings are abstracted.

In Kotlin, classes that possess abstract functions are termed abstract classes. An abstract class is like the pearl inside an oyster, housing at least one abstract function. Each abstract function in an abstract class awaits its implementation in subclasses.

Consider this simple example:
