Convert android studio environment from kotlin to java

Eva :

I'm still beginner in android studio ,and I'm asking if I can change the whole android studio code files from kotlin to java ?!

Nils Walker :

I think converting the whole project from kotlin to java isn't possible.

You can convert single Kotlin files to Java

Or you can convert the whole project from Java to Kotlin.

However, I would not convert anything and just stay on Kotlin.
