Sealed classes can restrict which other classes are able to implement them. In this case, the child or subclass can be of any type, a data class, an object, a regular class, or another sealed class. This allows you to define subclasses within the scope of the parent function, allowing you to represent hierarchies.

Sealed classes represent a restricted class hierarchy. Using sealed classes with the when expression.What’s the difference between sealed and enum classes?.In this guide, we will learn the concept of sealed classes and how to use them in Kotlin. For example, Kotlin has sealed classes, data classes, abstract classes, and enum classes that let you dive deeper and explore that class’s options. Kotlin even offers different higher-level concepts to write classes. The concept of classes goes wide and deep. A class defines all the properties and the behavior of an object. In simple terms, an object implements the actual class blueprint. Think of a class as set design and the object as the implementation of that design.

Like any object-oriented programming language, Kotlin employs features such as classes and objects in its codebase. Kotlin employs the features of object-oriented programming and functional programming concepts, which allows Kotlin to focus on simplifying its code while maintaining code safety. It is a very easy and friendly language to learn that is also simple to maintain and debug. Kotlin is a modern, open source language for developing multiplatform mobile applications. Joseph is fluent in Android mobile application development.
