Description: The type hierarchy in Kotlin refers to the organization of data types in a hierarchical structure that allows inheritance and code reuse. In Kotlin, all types, whether primitive or reference, derive from a common base class called ‘Any’. This hierarchical structure facilitates the creation of relationships between different types, allowing a child type to inherit properties and methods from its parent type. Additionally, Kotlin implements a type system that is safe and static, meaning that type errors can be detected at compile time, thus improving the robustness of the code. The type hierarchy also enables polymorphism, where an object can be treated as an instance of its parent type, providing flexibility and extensibility in software design. This organization is fundamental to object-oriented programming, as it allows developers to create complex data structures and maintain clean and organized code.
