What type of visibility does a public method in a class have in ABAP?

In ABAP, a public method in a class has visibility that allows it to be accessed from any class throughout the application. This means that once a method is declared as public, it can be called not only within the class it resides in but also externally by other classes, including those in different packages.

This level of visibility is crucial for enabling interoperability between different components of an application. Public methods serve as interfaces through which other parts of the program can interact with the objects of the class, fostering modular design and reusability.

The other options focus on more restricted scopes, such as access limited to the same package, subclasses, or only within the class itself, which do not apply to public methods in ABAP. Public methods are designed specifically for broader accessibility, differentiating them clearly from other types of method visibility that enforce stricter access controls within the overall system architecture.
