# Packages

Packages are a mechanism for organizing related classes, interfaces, and sub-packages into a hierarchical namespace. They act like folders in a file system, allowing developers to group functional components together to improve code maintainability and avoid naming conflicts. By grouping related types, packages also provide a way to control access levels, as classes within the same package can have specialized visibility to each other.
