Hi all!
I have a basic doubt but I'm stuck with it... How can I continue and accept an empty input? using this:
val scanner = Scanner(<http://System.in|System.in>)
 val myNum = scanner.nextInt()

I must always insert a number for programm to continue. But I wanted to insert nothing and just press enter for the programm to continue. And this way, myNum val would be empty
 been googling it, but I think I'm not knowing how to search for it correctly..

Hi, you probably want nullable integer - `Int?` . By using `nextLine`, feeding newline will cause the scanner to stop reading
```    val scanner = Scanner(System.`in`)
    val myNum = scanner.nextLine().toIntOrNull()```

yes, I can work with this! :smile: thank you!
