CamelCase in Scala

Example for versions Scala 2.8.0-final

This example uses regular expressions twice. First one, words, describes the words in the text; each match of it is replaced with itself, converted to lower case and capitalized. Second one, separators, describes the spaces between words; all matches of it are replaced with empty string, i.e., just removed from the string. 

import java.io.{BufferedReader, InputStreamReader}
import scala.util.matching.Regex
 
object Main {
    def main(args: Array[String]) {
        var stdin = new BufferedReader(new InputStreamReader(System.in));
        var text = stdin.readLine();
        val words = """([a-zA-Z]+)""".r
        text = words.replaceAllIn(text, m => m.matched.toLowerCase.capitalize)
        val separators = """([^a-zA-Z]+)""".r
        text = separators.replaceAllIn(text, "");
        println(text);
    }
