Do we need to create "kotlin" folder if there are both types of classes in the project, what is the benefit?


#1

Currently we could mix our java files with the kotlin files in the same folder. As far as I know it was not allowed some times ago and we had to create a special “kotlin” folder for them.

I wonder if there is any benefit to split java and kotlin classes by different folders(kotlin and java) if the project includes both.
Currently I see only the weakness that I will need to jump between the folders instead of having a mix of files in appropriate folder followed some business logic.

No, there is no benefit.
