Ada breaks object-oriented programming into separate features like encapsulation, reuse, inheritance, abstract interfaces, type extension, and dynamic dispatch, allowing opt-in.
In Ada, package specifications and bodies are separate, providing clear visibility and compile-time structure.
Ada requires explicit declarations for type extension and null records, preventing implicit assumptions.
Memory management in Ada uses controlled types with Finalize for automatic cleanup, similar to RAII in C++.
Ada uses package-based visibility control instead of class-based visibility, allowing child packages to access parent internals.
Constructors in Ada are functions returning objects, but can be problematic for inheritance; child packages or child functions can avoid primitive operation inheritance.
The prefixed method call syntax in Ada is syntactic sugar; dynamic dispatch requires class-wide types, not the syntax itself.
Ada competes with C, not Java, and offers safer and more expressive alternatives to C's memory management.
