Question
Which of these is a mechanism for naming and visibility control of a class and its content?OptionsPackagesObjectInterfacesNone of the Mentioned.
Solution
The mechanism for naming and visibility control of a class and its content is "Packages".
Here's why:
-
Packages: In programming, a package is a namespace that organizes a set of related classes and interfaces. It helps to manage the files within Java projects, and provide access protection and namespace management. So, it's the correct answer.
-
Object: An object is an instance of a class. It doesn't provide a mechanism for naming and visibility control of a class and its content.
-
Interfaces: An interface is a reference type in Java, similar to a class, that can contain only constants, method signatures, default methods, static methods, and nested types. It doesn't provide a mechanism for naming and visibility control of a class and its content.
-
None of the Mentioned: This option is incorrect because "Packages" is mentioned and it's the correct answer.
