Answer 1

I'm not sure what issue you have. Are you looking for something like this?

var num = 0 // Int
var num = 0.0 // Double
var num = '' // Char
var num = "" // String

Answer 2

tetsuya ,

this should work:

fun main(args: Array<String>) {
var name: String
//other code ...
name = "tom"
// other code ...
println(name)
}
