Kotlin does not allow this option. But you can do it the following way (definitely is not clean as in Java): https://code.sololearn.com/cY4JZAzhppI8/?ref=app

hinanawi yes, in this case I can assign before printing there is no harm but if have condition like this : while (fetching some data and != null ) something=fetch data again; insted of that if I write something like this : while(save fatched data to var != null) something = assign saved data then it can significantly reduce fetching time because it will fetch data only once.

When I do something like that, I do it this way: var data = fetch() while (data != null) { process(data) data = fetch() }

Tanay afraid it can't do that. not to knowledgeable about kotlin, but as it seems from the errors, a statement cannot be put inside a print statement. you can just put "f = 22f" in the line before, don't see anything wrong with that
