Answer 1

Kotlin does not allow this option. But you can do it the following way (definitely is not clean as in Java):

Answer 2

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.

Answer 3

I have just started learning kotlin today so didn't even reached till loop so just asking if I can write the experience like this in while loop or not.

Answer 4

I mean it should assign 22 to f before printing it.....can I write this kind of expression in println.

Answer 5

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

Answer 6

which assignment are you talking about?

Answer 7

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
