When I do a file new in my IntelliJ idea. I see a menu like this one
I want to see classes from Java and Scala on the top. I don't want to uninstall plugins for ruby etc. But these should not be on the top. I mostly code in java and scala and therefore want these classes to be one top.
Please ensure that the directory you're creating a class in is under a module source root. You can navigate to it in Project View, right-click on it or any its parent and choose Mark As... | Source Root
