Analysis on the difference between C# namespace and java package

This article analyzes the difference between C# namespace and Java packages. Share it for your reference. The specific analysis is as follows:

Similarities:

1. All are for reuseability - a very important goal in software engineering.

2. The namespace in C# and the packages in Java both belong to the access control mechanism.

Differences:

1. The C# namespace is just a logical structure, which allows the physical storage location of the organized class files to be inconsistent with the logical structure, while the physical structure of the class files in Java must be consistent with the logical structure.

2. Java package itself does not have the concept of subpackages. All packages are parallel relationships, and no one contains anyone’s problem. For example: There is absolutely no relationship between packages and sub-packages between them. They are their own independent packages, each with their own collection of class/interfaces. In a Java file, if you want to reference a class/interface, you must import.

The namespace solution of C++/C# is not the case. A namespace can have its own sub-namespace. We might as well call namespace packages, so there may be a relationship between packages and subpackages between packages in C++/C#.

3. Use import statements in Java and use namespace statements in C#.

I hope this article will be helpful to everyone's C# programming.
