Access Modifiers: Public, Private, Protected, and Internal Scope of Data Visibility in 22 Languages

By Theophilus Edet

Control the Gateways to Your Code

What do public, private, protected, and internal really mean across languages-and how do they shape your system's safety, scalability, and structure?

A Deep Dive into Access Control Across 22 Languages

In Access Modifiers: Public, Private, Protected, and Internal Scope of Data Visibility in 22 Languages, discover how data visibility rules vary across object-oriented, functional, procedural, and declarative paradigms-from Ada and Kotlin to Rust, Elixir, and XSLT.

Write Safer, Smarter, More Modular Code

Through 6 parts and 24 practical modules, this book explores how access modifiers function in real-world scenarios. Learn the design intent behind lexical scoping, inheritance-based visibility, internal/package-level access, and accessor methods. See how language design philosophies-like Python's "consenting adults" model or Swift's strict module boundaries-shape access control.

Gain Cross-Language Mastery of Visibility

Written in a technical-informal, explanatory tone, this book gives you the clarity and depth to understand and apply visibility rules consistently. Whether you're developing secure APIs, refactoring legacy systems, or scaling modular codebases, this guide equips you with the tools to think and code defensively across ecosystems.
