The restriction is that you can only have one top level public class per file (you can have nested public classes though). As people have mentioned you can have inner/nested classes within that class. Generally one class per file but can depends on the use of the class, if it represents and object in the business layer then one class per file, however utlility methods may be separated into separate classes but be contained in one file. Oct 05,  · OTHO, 'one class per file' is a standard idiom in Java and IIRC in C++ (which both have namespaces one way or another) In Java you don't get a choice, because the compiler assumes a class can be found in the correspondingly named file. While C++ has namespaces, they don't have any defined relationship to source files, so they don't help you.

Having one set of header/source files per class in a directory can seem overkill. with templated code, but I saw similar problems with regular C++ and C code. In C++ you have full flexibility how you want to organize your files. But you have to get accustomed to this freedom to make the good choices: A.

Another vote for one class per file with the file being named the same as the class. For me, it helps with long term maintainability. I can easily look through the repository and see what classes are part of a solution without having to open the project or any of the files. While the one class per file policy is strictly enforced in Java, it's not required by C#. However, it's generally a good idea. I typically break this rule if I have a very small helper class that is only used by the main class, but I prefer to do that as a nested inner class for clarity's sake. Generally one class per file but can depends on the use of the class, if it represents and object in the business layer then one class per file, however utlility methods may be separated into separate classes but be contained in one file.
