Top-Level Classes
Top-level classes are classes that are not nested within other classes or structures in object-oriented programming languages, existing at the outermost scope of a file or module. They serve as the primary building blocks for defining objects and organizing code, often representing core entities or functionalities in an application. This concept is fundamental in languages like Java, C#, and Python, where it influences code structure, accessibility, and modularity.
Developers should understand top-level classes to write clean, maintainable, and scalable code, as they form the backbone of object-oriented design in many programming languages. This is essential when creating standalone modules, libraries, or applications where classes need to be independently accessible and reusable. For example, in Java, top-level classes are required for defining public APIs, while in Python, they help structure scripts and packages effectively.
