What are the advantages of using packages?
Advantages of using Packages in Java

- Implement data encapsulation (or data-hiding).
- Provide controlled access: The access specifiers protected and default have access control on package level.
Which of the following are advantages of namespace in PHP?

Is namespace similar to package?
The main difference between namespace and package is that namespace is available in C# (. NET) to organize the classes so that it is easier to handle the application, while package is available in Java and groups similar type of classes and interfaces to improve code maintainability.
Is it important to know the namespace of a package?
The package namespace (as recorded in the NAMESPACE file) is one of the more confusing parts of building a package. It’s a fairly advanced topic, and by-and-large, not that important if you’re only developing packages for yourself. However, understanding namespaces is vital if you plan to submit your package to CRAN.
Is the native namespace package compatible with pkg _ resources?
While native namespace packages and pkgutil-style namespace packages are largely compatible, pkg_resources-style namespace packages are not compatible with the other methods. It’s inadvisable to use different methods in different distributions that provide packages to the same namespace.
What should be included in the namespace.py file?
The __init__.py file for the namespace package needs to contain only the following: Every distribution that uses the namespace package must include an identical __init__.py. If any distribution does not, it will cause the namespace logic to fail and the other sub-packages will not be importable.
