Description: Sealed classes in Kotlin are a feature that allows restricting the class hierarchy to a limited set of types. This means that when a class is defined as sealed, only the subclasses declared within the same file can inherit from it. This feature is particularly useful for modeling states and behaviors in applications, as it provides stricter control over the instances that can be created. Sealed classes are ideal for representing a closed set of options, such as in the case of a response system where different types of possible responses exist. Additionally, by using sealed classes, type safety in the code is improved, as the compiler can exhaustively check the conditions and cases in which these classes are used. This reduces the likelihood of runtime errors and facilitates understanding of data flow in applications. In summary, sealed classes are a powerful tool in Kotlin that allows developers to create safer and more predictable class hierarchies, enhancing code readability and maintainability.
