Converting String arguments to Char in Scala

Question

Example code:

object test {
  def main(args: Array[String]) {
    println(args(0).toChar)
  }
}

I have two arguments. The first one is a single letter, whereas the second one is a sequence of letters.

How can I convert the first string argument to Char? I tried the toChar function, but without success (error: value toChar is not a member of String).

args(0).toCharArray converts a string to an array

if you are sure you want only the first char, try args(0).head or more safely: args(0).headOption

it would be a Array[Char] that way. the head function worked fine
