object Scala_String {
  def main(args: Array[String]): Unit = {
    val str = "The quick brown fox jumps over the lazy dog.";

    // Replace all the 'd' characters with 'f' characters.
    val new_str = str.replace('d', 'f');
    // Display the strings for comparison.
    println("Original string: " + str);
    println("New String: " + new_str);
  }
}
